Why this works:
Sometimes restarting your HomePod isn’t enough. If the software malfunction is significant enough, it might be necessary to reset the device completely to get rid of the problem.
Luckily, this process is not particularly difficult to complete.
Pro tip:
Even if it takes a while, keep holding down the top of your HomePod until it emits the beeps signifying the reset. If you remove your finger too early, the reset will not complete and you’ll need to redo this step completely.
