Teams app screen position
When using multiple screens, Teams will sometimes "snap" off the viewable screen, where I am unable to move or see the window.
Closing and reopening the app via Task Manager does not fix it.
The only workaround is by going to a single screen and then it "snaps back" into the viewable area.
Yes, this is very annoying, I get it almost every time i restart my computer.
To get it back you can press Alt+Space, then "Move", then Arrow+down and you can move it with your mouse where you want it.
