Flyout is not appearing correctly on Windows or Android

[davefxy]

After I updated the csproj file and removed the ItemSizingStrategy="MeasureFirstItem" from the CollectionView in WidgetsPanel (because ItemSizingStrategy causes the Android version to exit on startup), I noticed the Flyout only shows the Settings Icon on Windows and Android.
With some fiddling around with Styles and VisualStateManager, I could get the FlyoutItems to appear on the Windows version. However I was never able to get them to show on the Android.
I tested the Android app on a Galaxy Tab S7.
