Additional features, settings, or issues not covered by specific Microsoft Teams categories
Ok, this has gone way beyond negligent behavior to down right malicious, all Windows users in my organization are having issues with the new teams' notification not showing up like the classic one, and having to rely on their phones to be notified of a new message or call, and on top of that teams is now telling the few people who have stayed on the classic UI that it will be retired soon and that everyone will have to use the new broken teams, and before you make the same post again please note that I have gone beyond your suggested steps and have actually downloaded and installed the new teams from the Microsoft website on a new laptop with a fresh windows install, still the same issue.
PLEASE FIX THE ISSUES WITH THE NEW TEAMS BEFORE FORCING US TO USE IT.
