Uno Platform Android versions fails to run

I have started a test app to test out TabBar to replace my bottomNavigationBar as it is no longer available in Uno.Material. I have made a simple app that runs on Android, IOS, and UWP without issue. When I add the code in for Material- it runs fine on UWP and on IOS. However when I run it on Android, It will build and deploy but not run. Is there something else I need to do to get it run on Android? Note: I have Xamarin.AndroidX.AppCompat, and Xamarin.AndroidX.LifeCycle.LiveData installed per the instructions. I get the following error:

System.InvalidOperationException Message=Failed to load unoMaterialSample2.MainPage: System.MissingMethodException: Method not found: void Windows.UI.Xaml.UIElement.set_Name(string)

Here is my App.Xaml:

So- if anyone else runs into this, here is what I ended up doing to solve the issue. I had been ignoring the visual studio warning that Google Play indicates you need to compile with at least Android 11. Once I switched that in the Android project properties- voila - it compiled and is now working as expected.
