[papikupreman]

when i playing the pokemon it occasionaly asking for account. and the pokemon app doesn't work anymore.
I using google account to play. i already delete account on bluestack but when i play it sometimes asking for account. and if i use 2 account on bluestack it will force closed when catch pokemon.
so for now i only can add account >> pokemon go >> delete account. repeat it about 20 times today
