I entered the feedback page and signed in but, when I signed in, instead of showing my gamertag at the top, it showed my name, and after checking, I saw that it treated my account (my usual account, the one I have always used), and the account with my name as different accounts. Maybe it happened because of the account migration.
I hope you fix it soon. I want to post an idea.
