At times, there may be problems in synchronizing the game with the information from Facebook. If syncing is slow, we recommend the following:
- Unlink your Facebook profile from your account by going to Settings > Unlink from Facebook.
- Restart your device.
- Enter the application, log in with your email address and re-link your Facebook profile from Settings > Link to Facebook.
Keep in mind that if you have to uninstall the application, you will not lose your account information, since it is linked to your email address.
