Rating songs with Siri stopped working (iOS 15.1.1 Music app, not service)
Sorry if this is the wrong place--it's not at all obvious where this question belongs.
I've been using my iPhone and Siri to rate the songs in my music library. For months I've been playing the songs with the Music app on my iPhone (started on a 6S, currently on a 13) and rating them with "Hey Siri, rate this song [###] stars". It's been working great, including the start of today, with Siri responding "Okay, I've rated it a [###] out of 5" or "Okay, I've rated it [###] stars".
Some time today that stopped working. The only responses I get now are "Sorry, I can't do that" or "Sorry, I can't help you with that". All other Music related commands still seem to work. I can rate the songs manually via the ••• menu.
I've tried turning data off and on, wi-fi off and on, restarting the phone, installing 15.1.1 update... Nothing works.
It was working, then it wasn't. No indication of what changed or what the problem is. This is incredibly frustrating.
The songs are played from a smart list called Unrated, but it also doesn't work if I navigate to the songs via Artists, Albums, Songs...
iPhone 13, iOS 15
