After upgrading Xamarin.Azure.NotificationHubs.Android Nuget from ancient 0.6 to 1.1.4.1 (which involves also upgrade from Support libs to AndroidX) in my App - Everything is OK without Azure Notification Hub and FireBase Nugets (and commenting code which use them). With these Azure/FCM NuGets I get Exception when starting App:

I had to add "Xamarin.Google.Dagger" NuGet, which is not listed in "Xamarin.Azure.NotificationHubs.Android" dependecies.
