So we've had this issue a couple times now since we upgraded to the latest version with Teams.
The old Skype interface pops up at login like it used to but if you click into it it will go full screen and attempt to look up users who's calls won't work because it's skype instead of teams, we can't close the window and nothing we know to do gets us out of it.
We've had to power off the device and reboot in order to clear the screen. Ending the session doesn't work and I can't find anything in reference to how to stop it. When there is a teams meeting to join it works just fine until you exit that teams meeting and the Skype call window is still running with no hope of exiting.
