Unfortunately, this issue has not been resolved yet.
When it tries to log you in, it doesn't recognise the email associated, which we are seeing as a robot error message.
If you associated a different email to your account when the YouTube sign in was still available (Like I did), your account will be fully associated and access will be granted with the other email.
Until this is sorted, I don't think you can get in guaranteed, so as you mentioned, please contact support and we will also try to keep you up to date with any new updates on this matter.
Sorry for the inconvenience.
