Sorry to hear you're having trouble with connecting your Facebook account and syncing your data. Here are some tips to help you troubleshoot through some of the problems players can sometimes see:
- If you get a 'No Connection' error then try again in about 5 minutes or later. This can depend heavily on the quality of your internet connection so WiFi is ideal.
- Once connected to Facebook, it may take a little time for the game to fully update with your data and that of your friends. Make sure that you're online, and once you've played a level or two, everything should have updated. Force closing and restarting the app may also help get you fully up to date more quickly.
- If your progress doesn't appear to be updating fully between devices try restarting the app on the original device while having access to an internet connection, to ensure that the most up-to-date data is uploaded properly before you access it on the secondary device.
