I have the new teams installed and when a user logs into an instant clone non-persistent desktop, teams will open but at the top it will have a red bar with a sign in error, if you click sign in button at the top right, it will then prompt for MFA and everything will work. Has anyone else had this and were you able to resolve it.
I am using FSLOGIX office container to hold teams data.
I also have a DEM profile setup to retain some of the settings that the office container does not, such as auto start teams on windows login.
