SFAuthenticationSession completion handler not called when using Azure Facebook Authentication

I'm implementing Facebook Login on my app using Azure B2C and I have to use SFAuthenticationSession to do this because FB doesn't allow it to run inside a WKWebView.

I'm basically trying to implement a SFAuthenticationSession with the URL that returns from my server side that is something like this:

https://companyName.b2clogin.com/companyName.onmicrosoft.com/oauth2/v2.0/authorize?client_id=xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx&nonce=xxxxxxx-xxxxx-xxxx-xxxxxx-xxxxxxxxxx&response_type=code&redirect_uri=https://myrul-qa.azurewebsites.net&response_mode=query&scope=offline_access%20openid%20xxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxx&state=xxxxxxx-xxxx-xxxx-xxxxx-xxxxxxxxxxxx&domain_hint=facebook.com&p=B2C_1_SiUpIn

The problem is, my completion handler is not getting called.

My code is basically this:

    var authSession: SFAuthenticationSession?

    func auth(url: URL) {

        authSession?.cancel()

        self.authSession = SFAuthenticationSession(url: url, callbackURLScheme: nil) { (url, error) in
            # this completion here is not getting called
            if error != nil { return }

            UIApplication.shared.open(url!)
        }

        self.authSession?.start()
    }

If I try this way, using the facebook URL instead of mine Azure B2C URL the completion is getting called: 

    func auth2() {
        let appID = Constant.facebookId

        var components = URLComponents()
        components.scheme = "https"
        components.host = "m.facebook.com"
        components.path = "/v2.11/dialog/oauth"

        let clientID = URLQueryItem(name: "client_id", value: appID)
        let display = URLQueryItem(name: "display", value: "touch")
        let redirectURI = URLQueryItem(name: "redirect_uri", value: "fb\(appID)://authorize/")

        components.queryItems = [clientID, display, redirectURI]

        self.authSession = SFAuthenticationSession(url: components.url!, callbackURLScheme: nil) { (url, _) in
            UIApplication.shared.open(url!)
        }

        self.authSession?.start()
    }

I expect that the completion can be called using my Azure B2C with SFAuthenticationSession.
