Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
With the 4K support offered by the roku 4 I had expected the Apple tv on both roku ultra and 4's if it didn't work on the 2 or 3 that's because they won't have 4K but sience Movies anywhere,HBO,vudu and most everything else is working with all the ROKU players back to the 2 it's just too bad we can't have it on all roku players more substantial subscription base for Apple tv+ if it were avaible on more devices and a show of good faith in the roku as the first device to get it!
You have to ask Apple about it. They are the ones that determine which Roku devices are supported. There's nothing Roku can do about it. It's the same with all channels. Only the channel developer can control the devices and geographical locations that their channel will work with.
