I have only 2 email address and the other one says that don't exist. I know from what email I migrated my mojang to Microsoft and what is my skin and nickname. But i dolnow my email and gamer tag. I only know avatar of gamer tag. I played it in the morning and I didn't log out and when I come back later in the afternoon I was logged out and email that is automatically filled in login say that there is no account with this login. I there any further for me?
