The app is still in a beta phase or at least it feels like it. Compared to a perfectly good app as hangouts was, it misses a lot of important functionalities. Functionality aside the user friendliness is also lacking. Why my rooms are in different tab than my 1-1 conversations, why can't I see the notifications of all my chats in a glance? This app wasn't ready in any way to replace hangouts and there is no real alternative now 😢
