Apple released a new software update for the HomePod and the HomePod mini. The update version is 15.4.1
This update addresses an issue where some HomeKit-enabled accessories could fail to respond when controlled via Siri and various bug fixes.
Like me, if you had issues with some of your accessories not responding when using Siri or resulting in a long response time for this update should fix that issue.
The update also extends Siri voice recognition to new languages. The update also brings the usual performance and stability improvements.
The size of the update come is 467 .7 MB
