We are also having multiple users reporting issues with teams, and what we are finding they all have in common is that they all have mac computers. The error message I get says: Something went wrong - you cant make or get calls right now. Ive tried redownloading the app, updating my computer, restarting my computer, allowing access again to the camera and microphone. (Which is incredibly frustrating because I want to use my laptop to see everyone on the call/share screens/etc). I am now not even able to JOIN a meeting at all using my laptop, but I am able to using my phone. It stopped working and I have not been able to get it to work since. I went into my laptop settings and allowed the camera permission to use Teams. When I originally downloaded Teams to my laptop, I was able to get on and have meetings but my video wasnt working. I have a Macbook Air and I am trying to use Microsoft Teams to have video meetings. I've basically exhausted all of my options, so hopefully I can find help here.
