I'm currently using the Xamarin.Social component to use Facebook login to my app. The problem I'm having is if a user chooses to deny Facebook permissions when logging in through the app for first time, the component just seems to get stuck in a loop. It will say "Authentication Error", go to the redirect url, then just go back to the Facebook login or permission request. It never seems to return back to the calling code in this case. I would like to be able to detect this and redirect them to the appropriate screen. Is there any way to do this?
