Mobile notification for already read notifications
Sometimes I get notifications on mobile but before I get to look at them (within about a second) they get removed because they are already read on desktop. So the problem here is that the notification seems to be triggered before the check to see if it has already been read (the message was read well before the notification was triggered).
I'm using the Android version of the app so I'm able to tell that it is Teams causing the notification only by checking the notification log.

I get notifications on Android when ACTIVELY chatting with someone on the desktop.
My desktop client is open, active and focused, yet I get notifications on mobile for the messages I receive in the active chat window.
That's right. If my phone is not connected to the internet and I turn it back on, Teams goes crazy by pushing me notifications about all messages - thought they have been already read on desktop.
