I just changed to a new Windows 10 computer and set it all up fresh from start.
I've connected it to my business account and all, got the Office apps to work but not Teams.
I've downloaded the MS Teams app and istalled it but when it freezes when I've entered my credentials and began to login. I've uninstalled it and restarted the computer, it's the same.
Tried to login to the Teams webb and then I got in a loop when I enter my credentials the text in the addressbar begin to flip and after a while I'm back to the screen
Pick an account
We couldn't sign you in. Please try again.
And I can see my usual work account.. Press it and then I get back to the same screen in a while.
Tried to press login to a different account and enter my credentials again, but no, same issue.
I tried different webbrowser, edge, Ie 11 and Chrome, same issue..
