I am following the steps mentioned in this link to create a remote event receiver within our SharePoint online site collection @ https://www.enjoysharepoint.com/create-remote-event-receiver-sharepoint-online/

and within AppEventReceiver.svc I define attaching the application in ItemUpdated and ItemUpdating as follows:

public class AppEventReceiver : IRemoteEventService
    {
        /// 

        /// Handles app events that occur after the app is installed or upgraded, or when app is being uninstalled.
        /// 
        /// Holds information about the app event.
        /// Holds information returned from the app event.

        public SPRemoteEventResult ProcessEvent(SPRemoteEventProperties properties)
        {
            SPRemoteEventResult result = new SPRemoteEventResult();
            if (properties.EventType == SPRemoteEventType.AppInstalled)
            {
                using (ClientContext clientContext = TokenHelper.CreateAppEventClientContext(properties, false))
                {
                    if (clientContext != null)
                    {
                        //Get reference to the host web list with name Feedback
                        var documentsList = clientContext.Web.Lists.GetByTitle("Project Update System");
                        clientContext.Load(documentsList);
                        clientContext.ExecuteQuery();
                        string remoteUrl = "https://tpusrer.azurewebsites.net/Services/TPUSRemoteEventReceiver.svc";
                                                  //Create the remote event receiver definition
                        EventReceiverDefinitionCreationInformation newEventReceiver = new EventReceiverDefinitionCreationInformation()
                        {
                            EventType = EventReceiverType.ItemUpdated,
                            ReceiverAssembly = Assembly.GetExecutingAssembly().FullName,

                            ReceiverUrl = remoteUrl,
                            SequenceNumber = 15002
                        };
                        //Add the remote event receiver to the host web list
                        documentsList.EventReceivers.Add(newEventReceiver);
                        EventReceiverDefinitionCreationInformation newEventReceiver2 = new EventReceiverDefinitionCreationInformation()
                        {
                            EventType = EventReceiverType.ItemUpdating,
                            ReceiverAssembly = Assembly.GetExecutingAssembly().FullName,
                            ReceiverName = "TPUSRemoteEventReceiver2",
                            ReceiverClass = "TPUSRemoteEventReceiver2",

                        };
                        //Add the remote event receiver to the host web list
                        documentsList.EventReceivers.Add(newEventReceiver2);
                        clientContext.ExecuteQuery();
                    }
                }
            }
            else if (properties.EventType == SPRemoteEventType.AppUninstalling)
            {
                using (ClientContext clientContext = TokenHelper.CreateAppEventClientContext(properties, false))
                {
                    var list = clientContext.Web.Lists.GetByTitle("Project Update System");
                    clientContext.Load(list);
                    clientContext.ExecuteQuery();
                    EventReceiverDefinitionCollection erdc = list.EventReceivers;
                    clientContext.Load(erdc);
                    clientContext.ExecuteQuery();
                    List toDelete = new List();
                    foreach (EventReceiverDefinition erd in erdc)
                    {
                        if (erd.ReceiverName == "TPUSRemoteEventReceiver")
{
                            toDelete.Add(erd);
                        }
                    }

                    //Delete the remote event receiver from the list, when the app gets uninstalled

                    foreach (EventReceiverDefinition item in toDelete)
                    {
                        item.DeleteObject();
                        clientContext.ExecuteQuery();
                    }
                }
            }
            return result;
        }

        /// 

        /// This method is a required placeholder, but is not used by app events.
        /// 
        /// Unused.

        public void ProcessOneWayEvent(SPRemoteEventProperties properties)
        {
            throw new NotImplementedException();
        }
    }

and when I check the remote event receivers connected to the list using this PnP script, I got the 2 RERs:

Get-PnPEventReceiver -List "Project Update System"

But when I update an item in the list, the ItemUpdated RER will work fine, but the ItemUpdating will have no effect. Here is the code for the ItemUpdating RER: –

public SPRemoteEventResult ProcessEvent(SPRemoteEventProperties properties)
{
    int listItemID = properties.ItemEventProperties.ListItemId;
    string siteUrl = properties.ItemEventProperties.WebUrl;

    SPRemoteEventResult result = new SPRemoteEventResult();
    string errormessage = "";

    using (ClientContext context = TokenHelper.CreateRemoteEventReceiverClientContext(properties))
    {
        CamlQuery camlQuery = new CamlQuery();
        camlQuery.ViewXml = string.Format("{0}", listItemID);
        ListItemCollection collListItem = context.Web.Lists.GetByTitle("Project Update System").GetItems(camlQuery);
        context.Load(collListItem);
        context.Load(collListItem,
              items => items.Include(
                  item => item.Id,
                  item => item("ProjectDescription"),
                  item => item("ProjectOMSNumber"),
                  item => item("ProjectDateSinged"),
                  item => item("ProjectManHoursEstimated"),
                  item => item("ProjectStage"),
                  item => item("ProjectApproveDelay"),
                  item => item("ProjectClosureSummary"),
                  item => item("ProjectHasBeenDelayed"),
                  item => item("ProjectDateSinged"),

                  item => item("ProjectHasBeenDelayed"),
                  item => item("ProjectStatusFlag")
                  ));
        context.ExecuteQuery();
        context.Load(collListItem);

        foreach (ListItem i in collListItem)
        {
            //This for all the orders regardless if there are created from OMS or Manully7
            FieldUrlValue currenturl = i("ProjectLinkToOMS") != null ? (FieldUrlValue)i("ProjectLinkToOMS") : null;
            //var fff = properties.ItemEventProperties.AfterProperties("ProjectLinkToOMS");
            if (i("ProjectOMSID") != null && properties.ItemEventProperties.AfterProperties("ProjectOMSID") != null && (i("ProjectOMSID").ToString() != properties.ItemEventProperties.AfterProperties("ProjectOMSID").ToString()))
            //||
            //(i("ProjectLinkToOMS") != null && properties.ItemEventProperties.AfterProperties("ProjectLinkToOMS") != null && (!properties.ItemEventProperties.AfterProperties("ProjectLinkToOMS").ToString().Contains(currenturl.Url+","+currenturl.Url))))
            {

                errormessage = errormessage + "Unaithorized access";
            }


            if (i("ProjectOMSID") != null && !string.IsNullOrEmpty(i("ProjectOMSID").ToString()))//item created from OMS!
            {
                TaxonomyFieldValue currentcustomer = (TaxonomyFieldValue)i("ProjectCustomer");

                if (
                   properties.ItemEventProperties.AfterProperties.ContainsKey("ProjectDescription") && i("ProjectDescription") != null && properties.ItemEventProperties.AfterProperties("ProjectDescription") != null &&
                    (
                    Regex.Replace(Regex.Replace(i("ProjectDescription").ToString(), "<.*?>", String.Empty), @"p{C}+", String.Empty)
                    != Regex.Replace(Regex.Replace(properties.ItemEventProperties.AfterProperties("ProjectDescription").ToString(), "<.*?>", String.Empty), @"p{C}+", String.Empty)
                    )
                    )
                { errormessage = errormessage + "You are not authorized to update Description."; }

            }

            var vv = properties.ItemEventProperties.AfterProperties("ProjectCustomer");
            if (properties.ItemEventProperties.AfterProperties("ProjectStage") != null && properties.ItemEventProperties.AfterProperties("ProjectStage").ToString() == "Closed" && (properties.ItemEventProperties.AfterProperties("ProjectManHoursUsed") == null || properties.ItemEventProperties.AfterProperties("ProjectManHoursUsed").ToString() == string.Empty))
            {
                errormessage = errormessage + "You must enter Man Hour used before closing the project";
            }

            if (!string.IsNullOrEmpty(errormessage))
            {


                result.Status = SPRemoteEventServiceStatus.CancelWithError;
                result.ErrorMessage = errormessage;
            }

        }
    }

    return result;}

So, can anyone advise why the ItemUpdating RER is not firing? although it seems that it is registered and attached to the list.
