Why can’t I connect to Facebook?
Make sure that Facebook connection is enabled in Options. Also, you need to have the latest version of the Facebook application installed on your device. If you have, but still cannot log in, try reinstalling the Facebook app.Also, if you downloaded the game from Viber app, instead of Facebook you will have an option to connect to Viber. Facebook functionality will be unavailable in this case. Finally, starting from ver. 2.8, Facebook SDK no longer supports iOS 6, Android 4.0.3 and below. So if you keep getting the message that your operating system is not supported anymore, please upgrade your OS to the latest version.
