Routinely hangs or crashes. Even mundane actions like rotating the screen will crash it. This has occurred since I first started using the app in November. Not only hasn't this been addressed in all this time, new problems have been introduced: 1. Room avatars don't reliably update to signal when users enter and exit rooms; 2. Raising your hand often doesn't signal the room mods. I'm done; I've switched to Clubdeck on PC. This app simply isn't ready for primetime.
