We just had this problem. After a little bit of tinkering, we found the solution. If you don't have it connected to your play Google account, connect it so it saves your games and purchases. Then log out of that account. Go to your phone settings, find app settings. In plants vs zombies 2 app. Delete app data. When you open the game, it will have you set your age, name a player, and then connect to play Google account. If it has you try to connect before you create a player, cancel that until you create one. Then after you connect, you will have another player added.
