How can I log out someone who's using my Game Center account from another device?
So my friend got hacked and the guy who hijacked her account stays loged in to her account, and even if when she changes all her Game Center and apple account info it doesn't log the hacker out of her account...
So what can she do..? Please help us it's really important and urgent!
P.S the game is Clash of Clans.
