Just made aware of this thread. See this other thread where I recently provided some info on why the app does not behave as expected. 4K (HEVC Main 10 HDR) on QNAP Plex Media Server - #36 by MovieFan.Plex
@hanky Your HZW1504 is a supported device so it should work properly. Can you provide an image of the about screen from the app? Also provide the entire server log so I can look into it.
