I bought a HomePod back in late February. Set up was a breeze but I happened to notice that it would show up under the AirPlay device list for like a day or two and then completely disappear. The only way I could get it to show back up in the lists on my Macbook Pro and iPhone X was to unplug it and replug it back in. I contacted Apple about it and they replaced the unit and this new unit is showing signs of that happening too. Has anyone figured out why it does this? If so, what is the solution? We reset it, changed who could access the speaker and more. I'm not quite sure what to do and I'm only trying a few more things before I make Apple take it back and refund me because this is annoying.
