I have multiple Shield TV and while the Amazon Prime Video app appears on the "Customize channels" section of all of them I have one Shield TV where it does not. It is in my listing of apps and I can add it to my Favorites row but cannot add the channel as a row on my main screen. I've tried removing updates, cache, data, and disabling and re-enabling it (it is not possible to uninstall it the conventional way) but it still fails to appear as an option under "Customize channels." I verified the version is the same as the app on my other Shield TV's. Any suggestions would be appreciated.
I have the same problem :(
