The Livestream channel on the Apple TV app allows viewers to watch your events via their Apple TV device on their television. As of September 2022, the Livestream app on Roku is no longer supported.
Viewers can search for your account or event to watch your live streams or archived videos. Any public content that you stream to your Livestream event pages will be viewable on the tvOS app as well.
When you are logged into your Livestream account, navigate to Settings.
Select the Advanced tab on the left. Then under the Account Visibility section, make sure Always shown is selected. Then click Save at the bottom of the page. This will ensure your public content can be found on tvOS.
Any paid plan can prevent content from being discoverable in the tvOS app. Change the setting to Hidden from search or Hidden from search and Livestream.com if you do not want your content to be discoverable on the tvOS app.
