We can see that you are unable to stream Apple TV on your Roku devices and TVs. Could you tell us do you receive an error message or code? Have you tried the basic troubleshooting by removing the channel and see if it helps? When removing a channel, make sure to restart your Roku device before adding the channel back again to ensure a clean channel install.
We would recommend doing this from the Settings menu by navigating to Settings > System > Power (If you do not see a Power submenu, skip to the next step.) > System restart.
If you still see the issue persist, kindly provide us with more details. Does the issue only occur on this specific channel or all channels on your Roku device? What happen when you tried to access the channel? What troubleshooting steps have you already taken to try to resolve the issue?
