When you try to target Android 10 and also try to use Nuget to get the Xamarin.Forms.Maps package you will get these errors:
Severity Code Description Project File Line Suppression State
Error Package restore failed. Rolling back package changes for 'Test.Android'.
Error NU1107 Version conflict detected for Xamarin.Android.Support.Collections. Install/reference Xamarin.Android.Support.Collections 28.0.0.3 directly to project Test.Android to resolve this issue.

Anyone know how to get around this? Or if it is being fixed?
Perhaps I should use the Google maps nuget package?
