Not the OP but I do run Teams on Apple Silicon and it is still a bug-ridden mess. Crashes, rendering bugs, file attachment bugs. At least once a week, usually more. Searches fail to find results that I can manually locate by scrolling through the chat history. I have reinstalled the app more than once.

I have shared these observations in their feedback pop ups and I know Microsoft loves collecting telemetry. Why should they dedicate more money/resources to fix defects when it clearly hasn’t stopped them from growing their market share?

Teams is the first example I use to begrudgingly explain to someone that quality doesn’t matter.

As per the hypothesis I stated, I think your problem is running Teams on an Apple system. I'm not defending Microsoft releasing a shitty product here, but I think it's most likely they didn't bother to properly test/debug it for other OSes and configurations than "embracing Windows and the Office ecosystem".
