Fast Forward and Rewind problem

Hi,

I'm using an IR remote (Logitech Harmony) and when I try to fast forward or rewind a video in Plex (tvOS) it just jumps back to the info screen. The fast forward and rewind buttons on my remote are mapped to the Fast Forward and Rewind buttons of an Apple TV device, which works fine in Simplex and native Apple TV video viewing. Is anyone else experiencing this issue?
