Siri on Homepods no longer works for Apple Music controls.
I too have this issue.
I have 7 homepod minis throughout the house all playing the same music. Everything worked fine until Apple Intelligence was released. Now Siri on Homepods if totally useless.
I say "Hey Siri dislike this song." and it says "I found some web results if you ask from your iphone". It used to mark the song as "Suggest Less like this" and skip it.
If I say "Hey siri like this song" it gives me the same useless "I found some web results" message. It used to say "I told apple music you like this song" and marked it as a favorited song.
If I say "Hey Siri add this song to my favorites" it says "I cannot do that, the favorites playlist is uneditable". What The **** does that mean?
If I ask all these same commands from my iphone they work as expected. Did they push a change to homepod Siri to pull her smarts to try and make Apple Intelligence a wee bit smarter?
I have given it a few weeks now. Usually strange things like this will pop up on the homepod siri then correct themselves later. I fear apple has pulled engineers off their normal roles into Apple Intelligence to chase others. Can we please put them back on their regular roles? PLEASE!
