Within the last month or so we go the pop up to try the "new" Teams... The new APP is having so many issues!! We use it for conference calls, and myself and others are having issues where the notifications are not showing, or when invited to a meeting it won't let you "join". I keep having audio (microphone & speaker) issues which I NEVER had previously. I really DO NOT like it. I've switched back to the older version for now. I simply refuse to keep dealing with all these NEW issues with the NEW version! :( It's simply horrible!
