All I know is that the AMC app works on my Firestick, An LG smart TV, a Visio Smart TV, and on two different computers. AMC can find nothing wrong with their app that would affect Roku. Roku needs to let people know in advance of purchasing their product that not all streaming apps will work with their "platform" so they can make an informed decision before purchasing. And here is the funny thing. At one point I had the AMC+ app through Roku and it worked fine. After I canceled through Roku and resubscribed directly through AMC+ it suddenly had issues. No amount of deleting and reinstalling help. Hmmmmm. And it appears I am not the only one. Chuck
All Roku can do when you are using any channel app not created by Roku is relay to you whatever the channel's servers send to it, act on any keypresses you make which are direct Roku command keys, and relay any other keypresses on to the app.
The app's creators must program into the app how to respond to the various keypresses passed to it.
