I'm getting the following error when trying to add a Google account (tried with 3 different accounts, 2 Inbox, 1 GMail, two of which are G Suite domains, 1 is a personal account):

The error occurs after entering credentials (after password or after 2FA, depending on the account).
Other than that, looks great! 馃憤
Working fine on macOS.
I'm experiencing exactly the same issue as benvddriessche.
Same for me.

Thanks for reporting everyone! We've located the issue and just uploading the new release now so should be live shortly...
Can confirm it's working with 3.1.1 馃憤
Working now. Thanks @Thomas101 for your fast response and solution!
