I had to play in my brothers device for a war cuz my phone died and I told him to log off afterwards. He didn’t. And he started playing it.Right now he upgraded my town hall 9 when I wasn’t even done upgrading my heroes. And dark troops.He is even wasting my hard earned gems. How do I kick him out of the acc?O ur parents say to resolve it ourselves, and he won’t let me near his phone. What do I do?
