I believe someone from Monzo answered this before. It was something along the lines of… they’re super cautious of putting ‘there’s a problem with x’ type notifications in app unless it is really important and affects a lot of people.
This is because they do see a surge in support queries from people asking what has happened, will x, y, or z be effected or asking for progress updates to name a few. I’ll have a quick search to see if I can find it.
Edit: I think this is the comment I was remembering
