No Connect / Link Device / Chat Options

Just to put this out there up front, no, it's not set to an underage account. It's my phone. When I log out of Game Center ID, then start the game to use the FB Connect option (I'm already logged on to the m.facebook site), it's not there. Just a new guest account that is stored on the phone.

I've uninstalled / reinstalled a few times (w/ restarts in between). Does anyone have any ideas? I know the FB Connect works, as this all works fine on my iPad; it's just flaking out on my iPhone. Same accounts, same Game Center ID, same Facebook ID used, etc.
