I’m not on the beta software with our HomePods but am on 26.3. We have not asked Siri to play any of our music in a while until today. Every playlist I ask it to play starts with “now playing that playlist “ and then the “there was a problem “ message. For some reason my wife got it to play when she asked it to play “library” but it refuses any specific playlist. I can ask it to play a radio station with no issue. I can start a playlist on my phone and hold it over one of the pods and it will pick it up and play it. It just seems that anything requiring a connection to our music in the cloud fails. Though why the library request was fulfilled I don’t know. Is there any way to fix this. We never had the problem before but haven’t attempted this for a couple of updates.
