I just got a 4K Fire Stick and can't find the Channels app. I have a server on my LAN for the DVR and have been using Channels on Apple and Android devices for years, I have another Fire TV and have Channels on that, but when I search for "Channels DVR" or "Channels app" on this Firestick, Channels does not show up in apps or apps and subscriptions at all.
Is there a problem with different model numbers or OS updates or changes that creates this issue? Or is there some known reason I can't find Channels on this Fire Stick?
