3 View Renderer IOS

[assembly: Xamarin.Forms.ExportRenderer(typeof(Tok.OpenTokView), typeof(Tok.iOS.OpenTokViewRenderer))]
namespace Tok.iOS
{
    public class OpenTokViewRenderer : Xamarin.Forms.Platform.iOS.ViewRenderer, IOpenTok
    {
        SessionDelegate _sessionDelegate;
        PublisherDelegate _publisherDelegate;
        SubscriberDelegate _subscriberDelegate;

        OTSession _session;
        OTPublisher _publisher;
        OTSubscriber _subscriber;
        protected OpenTokView _openTokView;

        protected override void OnElementChanged(Xamarin.Forms.Platform.iOS.ElementChangedEventArgs<Xamarin.Forms.View> e)
        {
            base.OnElementChanged(e);

            if (e.NewElement == null)
                return;

            _openTokView = e.NewElement as OpenTokView;

            var width = (float)UIScreen.MainScreen.Bounds.Size.Width;
            var height = (float)UIScreen.MainScreen.Bounds.Size.Height - 20;
            var view = new UIView(new RectangleF(0, 0, width, height));
            this.SetNativeControl(view);

            config = _openTokView.Init(this);
            _role = config.Role;

            DoConnect();
        }

4 PopToRoot Logic

        void NavigateToDash()
        {
            Device.BeginInvokeOnMainThread(() =>
            {
                try
                {
                    App.Logger.WriteLine("Call NavigateToDash");

                    myMaster.Instance.PopToRoot();
                }
                catch (Exception ex)
                {
                    App.LogIt("agChat:Failed to navigate - " + ex.Message);
                }
            });
        }

5 myMaster

  public async void PopToRoot()
        {
            IsDashboard = true;
            IsPresented = false;

            try
            {
                //Navigation View. =(
                await Nav.PopToRootAsync(false);
            }
            catch (Exception ex)
            {
                Nav.PopAsync(false);
                App.LogIt("ERROR: PopToRoot()", ex.Message);
            }

            PaintBar();
        }

Parent Page is where we call navigate.Pop(). Works in most other cases.
