HomePod can no longer find songs in my library

I'm running multiple first gen HomePods under version 18.0 through iOS 18.0.1. Since the last iOS update I am no longer able to access songs from my library. I used to be able to say, "hey, Siri, play songs from my library by (name of artist) and the HomePod would shuffle the tracks I had in my personal library by that artist (I subscribe to Apple Music). Now when I make that request Siri will say "I don't see any songs by (Name of Artist) in your Apple Music library, even when I have 100's of songs by the artist in question.

I reset Network settings on my phone, removed and factory re-installed ALL of my HomePods, but the problem persists. Any ideas?
