Createviewcontroller causing popup crashes

Hi guys,

I have a quick issue. I have been using the following code in my project for example:
So i create a page renderer (iOS) and put the following:

    public override void ViewDidAppear(bool animated)
    {
        base.ViewDidAppear(animated);

            Add(new ContentPageThatWorksIfSimplyUsingPushAsync().CreateViewController().View);
    }

The content page loads, the content loads. All is perfect! Seemingly.

If I PushAsync to a page that contains ANY Xamarin.Forms popup, the popup gets displayed twice (Whether its an actionsheet, an alert etc). Once I make the first selection, another popup is there waiting. Select the other popup and the app crashes with the error "The underlying Task is already in one of the three final states: RanToCompletion, Faulted, or Canceled."

i KNOW that the source of this nuisance is the code above because if I comment it all out the app works fine. Anybody have any ideas? If this is a bug its one that is a major pain in the butt.

Any insight?
