Teams is still broken. Sharing works intermittently. May be related to Chrome or window in full screen or another issue that hasn't been discovered until now. I don't have time to find a work around for this stuff.
I am on latest Catalina version and on the latest Teams version. I have restarted my mac and also granted all the required permissions.
Such a waste of my time!
i've spent hours with microsoft on the phone, rebooting, restarting, reinstalling, etc..etc.. these guys are completely useless, they won't just acknowledge the bug, instead they waste our time. it's so frustrating. they told me the issue is isolated
and no one else has the issue. i pointed them to this thread but they don't seem to understand. seems you need to spend days on the phone with support to get anywhere.
although it will probably get you nowhere, I do hope others try to open support requests with MS to get resolution.
