Apple’s 13.2 update reportedly came with an issue that resulted in the bricking of some HomePod units. Apple has pulled the 13.2 update and released the 13.2.1 update to fix the bricking problem.
This update includes all the features of the 13.2 but with a fix for the bricking problem.
The new music handoff feature makes it easier to switch between the device in your hand and the HomePod speakers. Just bring your phone close to the HomePod and a notification appears on the Lock screen asking if you want to play on HomePod.
You can update your HomePod by accessing it through the Home app on your iPhone, iPad, or Mac.
