Facebook Login web page does not redirect to the application at the first login

Does it happen with all facebook logins? Not sure that's the proper fix

Only with the first login, I mean if you did not login to Facebook on your device before.
In this case URL contains #_=_ and Auth0.resumeAuth(url, options: options) returns "false" (https://github.com/auth0/Auth0.swift/blob/master/Auth0/OAuth2Session.swift#L87) because items are a0_fragmentValues (_, _). But the URL is correct, it contains all necessary information (state, code) in NSURL.query

Also I checked "twitter", "google-oauth2", "linkedin". State and code are in NSURL.query, for these connections URL does not contain NSURL.fragment at all.
