The "more" icon is fine, IMO, but a bit of context is missing here. Why can users access without completing the registration? How is it possible that one has money waiting without completing the registration?
For now, I'll assume it's about money waiting to be collected. Without more context, I would classify the missing information as critical and there is nothing more critical to do. In this case, a simple plate will be easily lost. Especially in the case of certain users blind to color. Many will miss the difference between red and green, so their color scheme fails there.
I would suggest showing an alert explaining the problem and why an action is required when the user opens the application and would not allow the user to perform any other action until the required information is entered.
