DirecTV Stream "down" arrow stopped working.
I have a Harmony 650 universal remote that was working fine on my Gen 1 4K Apple TV (A1842) while using the DirecTV Stream app up until a few weeks ago.
As of recently, the "down" button to pull up information about a program, CC, and record is no longer working.
I can use the down button (and other directional buttons) outside the DirecTV stream app just fine. I can also use the directional buttons to move about the guide and other feature within the app just not while on a select program/show.
I also tested my Harmony Remote against my Gen 3 4K apple TV (A2737) and it continues to work just fine while using it within the DirecTV stream app.
Both Apple TV's are running the same tvOS (16.6) and the same DirecTV stream app 2002057667 (5.0.55).
The original 4K gen 1 apple TV remote does work (down arrow). Also apple hasn't updated their OS since July 24th 2023.
Since I cannot find a release date, nor do you tell customers when you update the app I can only assume the issue is on your end with the "latest" update.
Seems like your developers broke something for the Gen 1 4K Apple TV's with 3rd party remotes.
