To play this app, you must login via Facebook. Some users (not all) have reported that they are never presented with the Facebook login screen. It just returns to the launch screen.
The issue seems to be caused by Facebook Single Sign On (SSO). Currently, SSO_WITH_FALLBACK is used. I would like to change to SUPPRESS_SSO (not use single-sign-on).
And possibly update from Facebook SDK version 3.0.1 to the latest 3.14.
