[Couch co-op] Player 2 unable to use their own profile

It seems that Player 2 is unable to log in using their own profile and POE account, even though Xbox asks them to choose their profile when they press A to join. They can only access my characters and cannot create their own (any new character is created on my account)

Of course we made sure that Player 2 has a POE account which is linked to their Xbox account.

That could be an Early Access key issue, since their account doesn't have EA and only mine does, so I hope this is fixed in the full release.
