Apple TV + not working on Roku

I get a “Video not available. If this continues check your internet connection” on Apple TV on my Roku. All other streaming apps work perfectly. And I can stream Apple TV on my Mac at home using the same internet. This seems to be an issue many have asked about. What gives? I’ve restarted the Roku, uninstalled and reinstalled the Apple TV app. Checked the connection through Apple’s trouble shooting tool in the app itself. What’s going on?
