Trying to implemet uwp facebook integration

I have a test xaml uwp project in which I can login with facebook. the flow for this app is: -

  1. Press button to call an azure web service which handles the fb side of things
  2. Once the user has logged on it makes a protocol call and checks I wish to switch back to the app.
  3. OnActivated is called
    4 OnNavigatedto is called.

Within mongame obviously I have to do the call on the ui thread but steps one and 2 work but 3 and 4 never get called.]

Has anyone managed to get this working?

I have managed to get this working you cant use either Uwp Community toolkit or Azure auth you have to use the WebBrokerAuth if anyone else needs this let me know and will send you the code
