Why N2310 N4310 Plex have no new update and unable to install.
Due Plex asking APP release unity from Plex WEB directly, and we migrate to Plex web site in recently, thus please download latest Plex from:
https://plex.tv/downloads -> NAS -> Thecus -> POWERPC OS6
Then update from N2310/N4310 ADMIN WEB from OFFICIAL NAS APPLICATION interface directly.
