I can't log in to the game, I get an error.

Hey i got tge same thing whatj did was j updated  my phone and offloaded the app if doesn’t work then just delete the app and reinstall it as that way you’ll have the option to put in your information to login. I’m pretty sure it’s an error where the game can’t get a hold of your account information so what you have to do is delete the game and re-putting in your information so the  game can identify it again.
