Why some users do not receive an app invitation?
Before sending out the invitations, Facebook checks if the invited user has your app already installed. If so then this user will not receive the invitation. Additionally, the user will only be notified on platforms which are supported by your app. For example, if you support iOS and Android then the user will not see the invitation when browsing Facebook on the web using a PC. For iOS, you will need to specify iPhone store ID value in your Facebook app settings. If your app has not been published to the store, you can use ID of any published iOS app (you do not have to be developer of this app).
On iOS, my application crashes right after trying to log in.

Why am I always getting 'Failed to generate preview for user.' error when trying to share Open Graph story?.
This error is usually caused by sharing incorrect data. Make sure your Open Graph objects and actions are using namespaces and that you are providing values for all required properties of your Open Graph object.
