I tried to disconnect and reconnect from settings, of course. Nothing happens. It automatically reconnects, without asking password or permissions.
I thought I should try to uninstall everything, enable 2FA and reinstall everything but I thought to ask first here.
I use latest Windows 10-versions:
Windows 10 Insider 15055 (Desktop & UWP)
Windows 10 Enterprise 14393 (Desktop & UWP)
Windows 10 Mobile Insider 15055 (UWP)
