Accessing and using Microsoft Teams on smartphones and tablets across platforms
Not sure about the Authenticator app... It seems we have several setup possible here. Maybe tell us if you use Authenticator or Intune, with or without Work profile...
From my side, issue seems resolved when I use Teams in my personal profile, with Intune installed but not configured :) (Intune was mandatory, but I didn't log in there, and Teams works anyway !). I suspect my previous issue to be related to the VMware Hub in my Work profile, which lost network connectivity regularly and then my Teams in Work profile got blinking...
