Use Device Sync in the Settings menu to keep your progress in sync across all your devices.
To enable it open the settings menu and tap on the Enable button for Device Sync. Using Device Sync requires a login with Facebook, this is so we can use a unique identifier to link your devices together.
Note: Device Sync allows you to play across multiple devices, but players should not be playing on two devices at the same time, this could cause conflicts and all new progress may not be retained as you play on two devices at the same time.
Let us know if you run into any issues using Device Sync, we can help firstname.lastname@example.org
