If you are on the wrong level number, please make sure your game is currently connected to Facebook on both devices. It's very common for players to accidentally be disconnected from Facebook without them realizing it! You can check by tapping on the gear icon on the right side of the screen. This will bring up the Settings screen. 

If you are currently disconnected from Facebook, the big blue button on the screen will say "Connect". If this is what you see, tap on the Connect button to connect to Facebook. (Otherwise, don't touch it!) 

If you are currently connected to Facebook on both devices but your progress is still not synced, please follow these steps to reset the app:
