Recenlty in my last 2 versions on the google play i had this message. I know it says to look the migration guide but then i got these errors:

Failed to resolve: com.google.android.play:asset-delivery:2.2.2
Failed to resolve: com.google.android.play:asset-delivery-ktx:2.2.2
Failed to resolve: com.google.android.play:feature-delivery:2.1.0
etc...

I use the "com.google.android.play:core:1.10.3"
