The fact that the Teams interface changes now and then, does not help. I had a few times messages from other chats while being in a video meeting. Accidentally logging out of the meeting is just a click away.
That said, people complain a lot about Microsoft's software but the whole integration of Teams with the rest of the 365 suite (collaboration tools etc) still is superior to anything else I've used.
Can't figure out mute, crappy angle, bad lighting, noisy background, where is screen share? Where is chat? How to use breakout?
