HomePod music library error

Today i said hey Siri play some music. Which i have always done since the day i got 4 HomePod minis. And the usual response is “here’s a playlist just for you”

today was “there is nothing in your music library”

which is not true because i subscribe to Apple Music and have thousands of paid songs on my account. Anyone else deal with this / resolve

yes yes i can pick songs and play them but that is not what the question about, the question is about why does the HomePod routine change and how to fix.

thanks
