I'm in the process of learning Xamarin.Forms and Xamarin.Auth. I have followed this sample https://github.com/jsauve/OAuthTwoDemo.XForms and the instructions given by Joe at http://www.joesauve.com/using-xamarin-auth-with-xamarin-forms/. Authentication with Facebook works and I receive back the access token, etc. However, rather than being navigated back to the ProfilePage I get a white screen that includes the following content in red text.
"SECURITY WARNING: Please treat the URL above as you would your password and do not share it with anyone. See the Facebook Help Center for more information."
My experience with Xamarin.Forms and Xamarin.Auth is quite limited (as in just a few days) but it seems like Xamarin.Auth does not understand how to interpret the success. I've used Joe's exact code. I simply included my oauth creds for FB and I updated the Info.plist file according to FB's instructions.
Thanks,
Corey
