.net maui Navigation.PushAsync doesn't seem to do much

[wallym]

Let me start by saying that I assume that this is me.

I have a .net 8 maui project. I have a tabbed page and navigation page setup for each of my tabs. Inside of my imagelist page, I have two toolbar items as shown below. the toolbar items open the camera or the photo library on the device. When I run the code to open the next page, I don't see the next page beyond the title of the page changing. That is not the behavior I would expect. This is behavior I am seeing in the android emulator on Win11. How do I get the next screen to show up? I've tried several things but no luck. I've googled with no luck. any ideas are appreciated. I've made the picedit page just a label with text and no luck there either.

TIA

Tabbed Page:

    public class TabbedNavPage : Microsoft.Maui.Controls.TabbedPage
    {
        public TabbedNavPage() {
            On<Microsoft.Maui.Controls.PlatformConfiguration.Android>().SetToolbarPlacement(ToolbarPlacement.Bottom);
            var ratePage = new NavigationPage(new MainPage()) {
                Title = "Rate",
                IconImageSource = "rate.png"
            };
            var login = new NavigationPage(new Login()) {
                Title = "Login & Account",
                IconImageSource = "account.png"
            };
            var imageList = new NavigationPage(new ImageList()) {
                Title = "Image List",
                IconImageSource = "list.png"
            };
            var img = new NavigationPage(new PicEdit());

            Children.Add(ratePage);
            Children.Add(login);
            Children.Add(imageList);
            Children.Add(img);
}
}

Toolbar items:

<ContentPage.ToolbarItems>
    <ToolbarItem Text="Add from camera"
                x:Name="CameraAdd"
                IconImageSource="camera.png"
                Clicked="CameraAdd_Clicked"/>
    <ToolbarItem Text="Add from photo library"
                x:Name="PhotoLibraryAdd"
                IconImageSource="imagelist.png" 
                Clicked="PhotoLibraryAdd_Clicked"/>
</ContentPage.ToolbarItems>

code to open the camera:

private async void CameraAdd_Clicked(object sender, EventArgs e) {
    await GetImageEditorCameraSourceAsync();
}
private async Task GetImageEditorCameraSourceAsync() {
    var status = await Permissions.CheckStatusAsync<Permissions.Camera>();
    if (status != PermissionStatus.Granted) {
        // If the camera permission is not granted, request it.
        status = await Permissions.RequestAsync<Permissions.Camera>();
        if (status != PermissionStatus.Granted) {
            // If the camera permission is denied by the user,
            // You may show an alert or take appropriate action
            return;
        }
    }

    var photo = await MediaPicker.Default.CapturePhotoAsync();

    if (photo != null) {
        var img = ImageSource.FromStream(() => photo.OpenReadAsync().Result);
        await Navigation.PushAsync(new PicEdit() { ImageSource = img });
    }
}

The PicEdit page has gone thru various iterations of making this work. Here is what my most recent version is:

<ContentPage.Content>
<VerticalStackLayout>
        <Label Text="Hi" />
</VerticalStackLayout>
</ContentPage.Content>
