Some players have reported issues when connecting via Facebook such as being required to repeatedly connect. Please complete Level 1 before exiting the game or you may be reset and disconnected from Facebook which will cause you to receive a prompt to reconnect to Facebook. Additionally, this may be related to an update on Facebook's and Apple's privacy rules. 

The instructions below should help:

1. Disconnect and reconnect to Facebook (Account > Sign Out)
2. Clear the in-game cache (Settings > Delete Cache)
3. Ensure your game is still authenticated on Facebook. See here for more information. 
   

For Apple users still experiencing issues after following the instructions above: 

1. Device Settings Page
2. Privacy & Security
3. Tracking
4. Toggle “On” for the app or enable "Allow Apps to Request to Track".
5. Relaunch the app and log into Facebook.

Finally, if you're still having difficulty, please submit a ticket in the app to our customer support team.
