Doesn't seem to work right with Facebook.

It will authenticate, but following that you only get a white screen with the red text mentioned in the other posts.

It's worth noting that the Android app works slightly better. For some odd reason you have to login to FB twice but on the second time it will properly redirect to the Profile page.

Yeah, not really sure. My application is Instagram-centric, not FB. I followed Instagram's OAuth2 documentation. OAuth2 should work the same everywhere, unless FB does something weird that's different than other OAuth2 providers.

I am going to include the Xam.Auth source in my project later today and dig a little deeper. I will provide some feedback if I find anything. Thanks Joe!
