My cousin (I'll call them cousin1) can't migrate their account. I don't know why, we tried literally everything that this must be a bug. My cousin made his premium account with the same email as my other cousin(I'll call them cousin2). Cousin2 migrated their account, but because of that Cousin1 can't for some reason. Somehow, I had two premium accounts with the same email, and they BOTH migrated fine, but for some reason Cousin1's account can't be migrated. I'm 100% sure this is a bug because it works with my 2 old premium accounts that I got migrated, but Cousin2 could migrate their account while Cousin1 can't and they used the same email for premium.

The error says his email, password, or username is incorrect.

What we tried:

• Creating a completely new email (how I got my second account migrated.)
• Using email in username section
• Using all of Cousin1's emails
• Using all of Cousin1's password
• Tried all of Cousin1's passwords with all Cousin1's emails
