Connection errors can happen seemingly at random. Even with a strong internet connection, there may be other apps or services that are interfering with the game’s connection. We recommend shutting down the game completely (removing from recent apps) and launching again. If the problem persists, uninstalling and reinstalling the game can also fix this - don’t worry, as long as your game is linked to your Facebook account you will not lose your progress. Follow the General Troubleshooting Guide for more detailed instructions.
