You are not allowed to switch a game constantly between 2 devices. The rule is one device one game. You run a big risk of being blocked by GI. Chose which game to play on which device and start a 2nd game on the other as.‘support’ game.On friday i left my cellphone at work. At home, used an android tablet to play airport city, synchronized. When i started the game today on my smartphone, it was back to where it was on friday. Anything i can do?
