After 5 months of solid performance my HomePod in the upstairs bathroom tells me that its "having a problem connecting to your Apple Music account" and prompts me to check the Home app. And when I do, it's always the same thing- it's missing my password. I long-press the icon, it takes me to the HomePod settings page, I type in the password, and there we go. Its working again. I have another HomePod downstairs in the living room, no problems, never has had this issue once, not ever. But the upstairs bathroom HomePod, different story, once a week it disconnects and requires me to re-enter the password. I haven't changed my Apple Music account at all, same password for years. Credit card info is up to date. No changes to wi-fi or networking, all the same for years. All firmware on the HomePod's and iPhone is up to date. Any ideas? It's driving me nuts.
