Navigation Issues

[enginerd73]

I need a page flow as follows:

MainPage -> SubPage1 -> SubPage2

builder.Services.AddSingleton<MainPage>();
builder.Services.AddTransient<SubPage1>();
builder.Services.AddTransient<SubPage2>();

Routing.RegisterRoute(nameof(MainPage), typeof(MainPage));
Routing.RegisterRoute(nameof(SubPage1), typeof(SubPage1));
Routing.RegisterRoute(nameof(SubPage2), typeof(SubPage2));

MainPage - button to SubPage1
SubPage1 - button to SubPage2
SubPage2 - button to go back to SubPage1

I've tried using both Page Routes and Navigation object as follows:

private void NavigateSubPage1_Clicked(object sender, EventArgs e)
    {
        //Shell.Current.GoToAsync(nameof(SubPage1));
        Navigation.PushAsync(new SubPage1());
    }

private void NavigateSubPage2_Clicked(object sender, EventArgs e)
    {
        //Shell.Current.GoToAsync(nameof(SubPage2));
        Navigation.PushAsync(new SubPage2());
    }

private void NavigateSubPage1_Clicked(object sender, EventArgs e)
    {
        //Shell.Current.GoToAsync(nameof(SubPage1));
        Navigation.PopAsync();
    }

When the button is clicked on SubPage2 to return to SubPage1 the code runs, but the user remains on SubPage2. If I inspect the Navigation object, I can see all three pages on the stack. Any ideas what I'm doing wrong?
