In the first 48 hours, I've already noticed a few glitches: 1. HomePod suddenly showed up in the iPhone Home.app as "No Response", and nothing I could do easily would fix it. I rebooted the iPhone and rebooted the HomePod, and still "No Response". I ended up removing the HomePod from my Home and setting it up from scratch again, and the "No Response" went away. Hopefully it will stay that way. 2. When using Google Play Music to AirPlay to HomePod, when you ask Siri to skip a track, it advances the track, but for some reason, it keeps the elapsed time the same. So if you were 1:10 into the first track and asked Siri to skip to the next track, it would skip but start playing at 1:10 on the second track. 3. I asked Siri to play something from Apple Music, and when I asked it to stop playing, I said "Hey Siri, Stop" and tried 5 or 6 times before I gave up and walked over to the HomePod to tap the top to stop the music. I know Siri could hear me, because the music volume would lower when the requests were being processed. Before I finally used a single tap to stop, I even tried using the verbal command while I was right next to HomePod, but it still didn't stop playing.
