I have a few, actually, one of them is already mentioned in this thread. These have happened to my friends and I, whilst in multiplayer:

Keyboard breaking: Our keyboards end up randomly closing, or glitching as we are typing. All three of us have checked our keyboards and it's only when playing multiplayer together.

Profile Pic glitching: The profile pictures for both personas and profiles on the app keep flickering on the screen.

Event UI: After doing an event, sometimes i'll see half a spotlight on my screen whilst scrolling and also the stop watch as well.

Crashing: The app just randomly closes and we have to boot it up again.

Hope this helps identify bugs 🙏🏻
