Xamarin Forms Advertisements : Platform switching best practice?

Question

Please spend 5 mins helping.

I started with Xamarin Forms, Android and implemented Google Advertisements at Forms xaml level (with an Ads control).

When I added a UWP project I notice the Google Ads are not working so my next step is to develop Microsoft Advertisements in UWP.

What is best practice?

Should I switch platform specific Ads in XAML, C#?

Should, in fact, Google Ads work in UWP?

Many thanks

https://montemagno.com/xamarin-forms-uwp-ads/ @James Montemagno will your example still work and is recommended? I need an 'Adrenderer' per platform.
https://learn.microsoft.com/en-us/windows/uwp/monetize/display-ads-in-your-app @James Montemagno or is this one better and should be accordingly coded?
