navigation issue : PopToRootAsync is not supported globally on iOS, please use a NavigationPage

On App class I have this : 

MainPage = new NavigationPage(new MainPage());

In MainPage OnAppearing :

protected async override void OnAppearing ()
    {
        base.OnAppearing ();

        if (TempUserInfo.IsNewUser ())
            await this.Navigation.PushModalAsync ( new SignUpPage ());
    }

On SignUpPage after user enters all information , I use this :

await this.Navigation.PushModalAsync (new VerificationCodePage());

Finally , after I check verification code on VerificationPage I used this: 

await this.Navigation.PopToRootAsync ();

Now , I'm getting this error :

PopToRootAsync is not supported globally on iOS, please use a NavigationPage.

What I want to achieve is exactly like this navigation setup above .

This solution worked as i expected on Android. Put these in App.xaml.cs

 public static MyMasterDetail RootPage()
{
    return (MyMasterDetail)Current.MainPage;
}

public static void NavigateToHomePage()
{
    try
    {


        MainPage homePage = new MainPage();
        MyMasterDetail masterDetailRootPage = (MyMasterDetail)Application.Current.MainPage;
        masterDetailRootPage.Detail = new NavigationPage(homePage);
        masterDetailRootPage.IsPresented = false;

        Current.MainPage = masterDetailRootPage;
    }
    catch (Exception ex)
    {
        Debug.WriteLine("!!! NavigateToHomePage() Exception !!!");
        Debug.WriteLine("Exception Description: " + ex);
    }
}

Then you could call from anywhere to go home

   App.NavigateToHomePage();

Or show masterdetail left side menu

   App.RootPage().IsPresented = true;

I resigned navigation to what Jason suggested and in the VerificationPage , I used this :

MainPage = new NavigationPage(new MainPage());

Thanks everyone for your help .

Instead of doing 

await this.Navigation.PopToRootAsync ();

You can reset the main page :

MainPage = new NavigationPage(new MainPage());
