Unity 5.3.1 issue with facebook sdk 6.2.2 on IOS

Hey there! I have just upgraded from Unity 5.3.0 to unity 5.3.1 . I am using facebook sdk 6.2.2 currently.

On unity 5.3.1 i am having multiple issues including not receiving any callbacks when i want to download the avatar.

global::FB.API("v2.0/me/picture?type=large", global::Facebook.HttpMethod.GET, (FBResult res) => { Log.Info("Avatar response received!"); if (res.Error == null) { callback(res.Texture); } else callback(null); });

Note : this was working on unity 5.3.0 and previous

Thanks!
