It seems I have the same problem now.
Following the tutorial procedure, after clicking the move my account I have the following message:
<<You already have an account in the new panel!
You will be able to login to old panel and new panel at the same time (Email address must be the same)>>
However if I login, in both cases I always enter in the old panel.
Should I follow the alternative suggestion of the tutorial and delete my profile? I would like to receive your confirmation before proceeding in such a critical step!
