Hi!
I'm facing the same problem.
If I search the community for my user (vandreytrindade) it appears my info, but everytime I login it asks for another username.
I have to create this one just to post in here as well.
There's no way to connect again to my regular user account? I haven't changed my mail address and my username doesn't have any dashes or underlines or whatever.
It's happening the same with my work mail address...
Any news about this???
