I've tried to use the Facebook iOS dialog request, but unfortunately the request is not showing up in the Facebook Mobile App.
Since then, I've tried to add a Page Canevas (with the same Facebook app id) and magically I've been able to receive notifications on my Facebook Internet account ("XXXX sent you a request"), but nothing in the Facebook Mobile App.
I've heard that I need an iPhone store ID to solve my problem. Hope you can help me.
