Apple has stopped the Home app upgrade due to issues reported by users

Apple has temporarily pulled the rollout of an optional Home app update after users began reporting problems with the software. The company says the update option will return soon; if you’ve already updated, the change won’t affect you.

This update was released along with iOS 16.2 and macOS Ventura 13.1 on December 13 and was an upgrade to the underlying HomeKit architecture. Apple said the redesign would make the platform more robust and efficient. However, some of those who installed the software quickly encountered problems, including individual Siri terms not working correctly and no display of smart home devices in the Home app. 

An Apple spokesperson said the company is aware of an issue that could affect users’ ability to share Home in the Home app and that a fix will be available soon.

If you have already installed this update, you will have to wait for Apple to release a software fix. Unfortunately, there is no way to revert to an older architecture.
