Thank you for your answer. I tried to log in into android tablet and it's a success, but on my iphone it's not working. But in android i don't see the all star tournament. So if i delete and install the app on my iphone i'm afraid il will lose the progress in the all star tournament. What should i do?
Also if i try to ask for live from friends in the app a message appear : restart required. dont delete or uninstall the game. How do i restart the app? without losing my progress and boosters?
