While trying to migrate my Destiny 2 account to Steam, it appeared that there was already a linked bungie account in my Steam account. But the account that is linked is not mine. How do I unlink this strange account from my Steam and link the correct account? Editing: I was able to link my real bungie account on Steam. But when I try to migrate the game it says that the account has already been used by someone else and I can't migrate my game. How should I proceed? Can you help me?
