Probably one important note to add here.

If you have page navigation and need to track back button pressed on the navigated page, you need to set the following in AndroidManifest.xml:
<application ... android:enableOnBackInvokedCallback="true">

Works fine with the latest MAUI update (8.0.10).

I don't think it is required, because you add callback OnCreate in Activity: OnBackPressedDispatcher.AddCallback(this, new BackPress(this));

Haven't worked for me when I used AppShell navigation and wanted to track back button click from the page navigated to by routing. Only android:enableOnBackInvokedCallback="true" helped me.
