I downloaded the Xamarin.Auth component and am running the sample app. It works well, if run by the Developer of the app (as defined by the Facebook Login).
If I define a tester, however, it never fires the "Completed" event. I had already seen a similar behavior with the Facebook SDK by "The Outercurve Foundation" where, after some tinkering, I managed to get it to display the "Successful Login" screen but with a non-oauth html address.
Is this a known bug or am I doing something wrong?
In addition to the question: the documentation for the Xamarin.Auth component is displaying an Application Exception. Where could I report this?
