HomePod stops playing after 2-3 hours since upgrade to 16.4
I have an original HomePod on my desk, which I use for background music while I'm working. In the morning I'll tell it to "shuffle the work playlist", and it would shuffle the songs from that playlist all day long, and continue playing all night if I happen to forget to pause it at the end of the day. In most cases I can un-pause it the next morning and it'll pick up where it left off, right in the middle of whatever song it was playing when I paused it the previous day. I've been doing this for several years (since I started working from home, which was when COVID started).
Since upgrading it to 16.4 a few days ago, it seems to stop playing 2-3 hours after I tell it to start. It doesn't just stop in the middle of a song - it's like it only chooses a certain number of songs to play, and once that list is finished, it stops.
It also isn't "pausing" itself, because if I tap the screen after it stops, it doesn't remember which playlist it had been playing 30 seconds prior, and it starts shuffling all music from my library.
I called Apple support about this earlier today. They walked me through the process of resetting the HomePod (i.e. unplug, wait 30 seconds, plug in, immediately press and hold the top until the circle turns red, then until the voice says "you are about to reset", then until it plays the three beeps), and once it was added back to the Home app on my iPhone then they said to "keep an eye on it and call us back if it happens again".
This was about 2-3 hours ago, and it just stopped playing again. (I'm going to start keeping a log of what time I told it to start and when it stopped, maybe there's a pattern and I'm just not seeing it because I don't have to think about it for
