In September 2017, Apple released a new version of the operating system for Apple TV 4th generation and later, tvOS 11. Since this release, the Home app for Apple tvOS has stopped functioning and will no longer be supported. The latest version of our tvOS app, version 1.1.1, will be the last release of our app on Apple TV and will no longer be updated. We apologize for any inconvenience that this may be causing.
