We’re all frustrated with this. I thought the issue was fixed. I had issue that Siri on HomePod couldn’t find Music , despite me being able to find directly via iPhone, iPad or from my Mac. Had a great tech conversation that lasted 2 hours, and indeed Apple is aware of the issue. Following day, it seemed to be fixed…..After working perfectly for less than an hour, suddenly stopped. I can stream from iPhone, iPad and Mac to HomePod speakers in several rooms…..but when I ask Siri to play from Music…..I get a response that there is ‘something wrong with my Apple account’. Which is strange as it works perfectly on the phone, iPad or Mac.
btw. The Tech checked that the HomePod software was up to date at14.5.
