If your account is currently synced to Facebook, Game Center, or Google, you will need to log into your account using correct login information. If you logged into the game with the incorrect information, you will need to log out, apply the correct credentials, then try again. In some cases, you will need to uninstall and reinstall the game.
If your account is synced to Facebook, you will need to download the Facebook app, sign into it with the correct information, and log into the app and select the Facebook option. If your account is synced to Facebook, and your Facebook account becomes blocked from use, you will need to contact Facebook support to regain access to it, as we are unable to unlink it from your game account.
If you have visited a country where either Facebook, Apple & Google-related services are banned, your account will not be able to load as it cannot obtain permissions needed to log into the game's servers. It is recommended to sync your game account to a login option that is allowed.
