I'm trying to use the example at https://components.xamarin.com/gettingstarted/facebook-sdk to post to my Facebook wall, but it keeps coming back t.IsFaulted = true. In other words it's not posting.
I got an authentication token using Xamarin.Auth but it doesn't seem to work.
I guess I need to request some extra permissions somehow or set them up on the app to be allowed to post to a wall, but I can't find anywhere how to do it.
Does anyone have any tips?
