Hi all,
I have the same problem as suikoy and iiolavoii.
Some times (means some years) ago I somehow could connect desktop and my phone. It worked for a long time now.
But today somehow the connection was lost.
And if I try to reconnect my phone (even if I scan the code from the mentioned homepage instead of the sidebar) after scanning the android smartphone shows the 6 digit confirmation code but the desktop jumps to "https://auth.opera.com/account/v3/desktop/login/login-success".
There is shown "Congratulation, succesfully logged in" and the question "What do you like to do now" with the 2 buttons "Your data is synchroniced" and "Manage subscriptions". That's all.
Meanwhile the code on the phone times out and then I can restart the whole procedure...
I would be grateful for help.
