It's very strange but I'm not able to complete the autenthication.. My android smartphone shows the 6 digit confirmation code but in the meantime the desktop jumps to https://auth.opera.com/account/v3/desktop/login/login-success...
This behaviour in both cases: with the QR code from the Flow panel or with the QR of the site opera.com/connect.
And the even strangest thing is that if I use Flow with my iPad everything works perfectly.
Perhaps it is a clue that the bug with Flow is caused when both the desktop PC and the Android smartphone are already connected with the same Opera account.
Any suggestions?
