    This morning I updated an existing app to use Xamarin.Forms 4.8.1269,, after the update the app would no longer build for Android. The following error appears : "Assembly 'Xamarin.Android.Support.v4' is using '[assembly: Android.IncludeAndroidResourcesFromAttribute]', which is no longer supported. Use a newer version of this NuGet package or notify the library author"

    After googling about the issue, I have updated the Android Project to the target the latest api which api 30. I have also updated all nuget packages to the latest version, this also include the latest version of visual studio.

    I am not sure how to resolve this issue and if any has seen or fixed this issue any assistance would be greatly appreciated.

    This morning I have rolled back the Xamarin.Forms package to the previous version and the issue is now gone.
