I noticed an update in the Play Store for Prime Video, so I looked under "What's New" and it says:
"Use the Android TV Remote Control app or your Bluetooth keyboard to search for the shows and movies..."
I tried, it doesn't work. All I can do is all I've ever been able to do and that's just navigate using the d-pad.
yep... tried with different remotes... i think is amazon's fault. You can search on your phone/pc etc add to wishlist and then it will be linked to your app. Does all i have manage so far.
