The issue with permissions to access Friends messages and lives is more concern to the permissions you allow on your Facebook app rather than with our games. Some players said that they had the App Visibility checked in private mode. So just changing that box it should be fixed.

Hopefully, with this you will back on track and to enjoy the game
