Copying WhatsApp chat history to new Android

There have been many questions asked and answered on this topic but unfortunately I’ve not found one that addresses my issue.
I have read that to transfer the WhatsApp chat history to a new phone it is necessary to first back up the chat history from the old phone (before removing the SIM) to Google Drive. Unfortunately I didn’t do this. I moved the SIM from my old to the new, installed WhatsApp and registered it with the old number, so losing all my chat history.

I assume that my chat history is still on my old phone but if I run it with a different SIM, WhatsApp presents me with the welcome screen and I have no way of accessing my chat history (I have not tried registering WhatsApp on the old phone with an new number). So I now have a chat history on both my old and new phones.

Is there any way to access the chat history from the old phone and combine it with that on the new phone.

Suppose I temporarily move my original SIM back to my old phone and get WhatsApp running again with the old number, will my chat history be restored? If so, I am thinking I could then do the Backup to Google Drive and then somehow combine the two histories on the new phone

How can I Stop receiving notifications from someone without opening theirs chat( Google Chat )

My Company uses Google Chat(G Suite) as an IM client.
I’m having trouble and don’t want to receive chat notifications from a specific person.

I want to clear the “Notifications” checkbox in the attached image

So I referred to the official help.
However, it seems that I can’t change the notification settings until I open a chat with the person.

  1. Go to Hangouts at or in Gmail.
  2. Click a contact or conversation.
  3. Click Settings.
  4. Untick Notifications.

As you know, Google Chat has “Read receipts”.
Once I open a chat, the opening notification will be shared with the person.

I am in a position to refuse any contact with the person,
so I don’t even want to know what I’ve read.

I just want to avoid opening chats and getting notifications from him, but is there any way?

No video chat button in Discord voice channels

I have set up a Discord server with several voice channels. I see no button for the video chat in the lower left corner, so it seems not to be possible to do video chat nor screen sharing. Voice is enabled: I see the microphone, headphone and settings icon.

I have gone into the Server Setting and the Roles there. For the “everyone” role I see connect, speak and video enabled. Also for another role that I have set up, these configuration setting are enabled.

I have other servers with Voice channels where I do see the “Video” and “Screen” button, it is apparently only for this particular channel.

Note a old Reddit post with a similar question:
