Update: Apple has released an updated version of the software which should resolve these issues.
“Apple today released new 13.2 software for the HomePod with long-awaited features like Handoff and voice detection for different family members, but unfortunately, some users are running into problems with the update.”
This is disgraceful. It’s not just that they don’t work, but that there is nothing users can do. Apple is having them ship them back to the company to get them fixed. All this because there’s no USB port to restore the device.
What a blunder.
(To be fair, it’s not clear how many people this is affecting. As often with this sort of problem, the media attention makes it appear bigger than it is. Mine both work fine after the update.)
