[dmanning23]

Thank you, the suggestions in the 764 ticket solved that issue.
I've had another similar issue come up when I add the following packages though:

	  <PackageReference Include="Xamarin.Google.Android.Play.Core">
	    <Version>1.10.3.14</Version>
	  </PackageReference>
	  <PackageReference Include="Xamarin.Google.Android.Play.Core.Common">
	    <Version>2.0.4.2</Version>
	  </PackageReference>

I'm working on a project where these 2 packages are added as transitive packages. These are the latest versions from Nuget, they are both published on the same day but the version numbers don't line up at all.

I've updated the example project to demonstrate these errors. When it is compiled, the following XA4215 errors are thrown:

Google deprecated Google.Android.Play.Core and split its code into separate packages like Google.Android.Play.Core.Common. Thus they contain the same code and cannot be used together. You will need to fully use one or the other.
