@Jerome-Liger Thanks for sharing you solution. I was having the same problem despite targeting Android 10 and setting up the code as described on the tutorial. After installing the following packages, the problem went away:

<PackageReference Include="Xamarin.Firebase.Messaging" Version="71.1740.1"/>
<PackageReference Include="Xamarin.GooglePlayServices.Tasks" Version="71.1601.1"/>
