Hi,
We have an Apple TV 4K and a Logitech Harmony Elite remote. The remote controls our smart TV, AV receiver, Apple TV 4K, PS4, Sky box etc.
Before Lightbox was upgraded the transport controls (Fast Forward, Rewind) worked fine. But now with the new Apple TV Lightbox app we can't fast forward or rewind using the Harmony Remote.
The touch surface of the Apple TV remote works fine with the new app. But our apple TV is in a media closet some distance from the TV, too far for the apple remote.
The Lightbox app on our smart TV (Sony Bravia / Android TV) works fine and we can FF/REW using the harmony remote, but it is a little clunky compare to the Apple TV app.

If anyone else has a Harmony remote and an Apple TV 4k can you check if you can FF and REW? I would like to know if it is our setup or something in the new Lightbox Apple TV app.

Just in case anyone asks....yes there are discreet FF and REW commands on the Apple TV despite no corresponding buttons on the remote. The Harmony remote can FF/REW on other Apple TV media apps (Plex, Netflix, TVNZ, TV3 etc.)

I think the problem maybe that Lightbox has not mapped the discrete FF/REW commands in the Apple TV (4K).

Marty.
