MasterDetailPage Navigation doesn't show the Hamburger menu after upgrading to Xamarin.Forms v188.8.131.5224
With Xamarin.Forms v184.108.40.20605, our master detail view looked like this
(note the hamburger menu and the title 'Menu' at the top)
With the latest update (XF v220.127.116.1124), the hamburger menu is no longer
visible, and there is a block of blue at the bottom - it looks like the
whole master section has shifted up and is hiding the hamburger menu.

Please change your NavigateTo method to:
public async void NavigateTo(ContentPage page)
await Navigation.PushAsync(new NavigationPage(page));
The hamburger menu will only appear with a NavigationPage. This is not a regression because the previous behavior was unexpected.
The NavigateTo method is actually not used in that sample. I did, however, change the MainView constructor to use a NavigationPage:
this.Detail = new NavigationPage(newDetailPage);
but there is still no hamburger menu. Please advise.
Oh, apologies! I see what you mean now. This is also by design--on the desktop/tablet, we default the MasterBehavior to Split. This negates the need for the hamburger icon altogether because the Master is always visible. That's the block you see on the left side there.
You may change this by changing the MasterBehavior property. For example, MasterBehavior.Popover will display the hamburger icon and hide the Master view until you click the icon again.
OK. so I think we can work with that. However, there still seems to be a layout issue. If you change the MainView.xaml to include a stacklayout set to FillAndExpand (and a different background color so you can see the problem), it appears that the stacklayout is shifted up, leaving a blue bar (looks about the same height as the hamburger menu/panel) at the bottom. In my case, I think the desired effect is that the background of the label would be blue, and the rest of the vertical space would be yellow
Here is the modified XAML:
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage Icon="slideout.png" Title="Menu" BackgroundColor="#03415F">
<Label Text="Dummy Label"></Label>
<StackLayout BackgroundColor="Yellow" VerticalOptions="FillAndExpand">
I'd be happy to attach/send a screen shot if that helps.
