Missing new messages

When you tap on a notification for an incoming message in another room, the Android app switches to that other room as a stack: the top-left back arrow gets one deeper in a stack of rooms.

Say you're in root <- room A <- room B. If you get a notification for a new message in room A, it doesn't appear in room A's history (ever). I have to switch to the web app to read those messages if I didn't remember them from the transitory notification text.
