I installed the Apple TV channel through the roku website, but it’s not installed on my TV. I have 4 roku devices on 4 tv’s all are different models. So why can’t I get the Apple TV ON AT LEAST one. Are you saying I have to buy another Roku device.
What model Rokus? Apple only wrote their channel app to work on later model Rokus with enhanced capabilities beyond those of some older units. It will only load on compatible units. See this article:
