on this device either refresh nor resolution switching seems to work at all
resolution on firetv cube is 2160/60p by default.
Plex Settings enabled refresh switch and resolution switch
now, when playback starts nothing happens, always stays on 2160/60p instead
1080/50 (LiveTV) or a sample movie 3840/24p …or 1080/24p …
now, some movies or tv records it would try to refresh but then the error occurs, cannot play … 
some logs attached
(File removed)
as note, other pleyers play all just fine including res and refresh swich … afaik also using exoplayer
may another while im on it, plex player shield tv device has the refresh issue with only with livetv, logs will follow …
