you can link your account to twitter or google play if your phone is rooted or you can also using transfer data code if you want to transfer your progress to other device
i just install the game from playstore in another device
edit: my account haven't been banned yet, i play it save tho, using 2x dmg and god mode but never play any stage that have more cp than my team
i'm trying to login with clean game files from play store and it seems fine, i can play normaly, no fc, not getting ban
i think it just they can detected modded apk now, so everytime you login using modded apk it will cause to crash the game
