If the Asustor app center doesn’t offer the updated server, you should be able to install it manually.
- download the version of PMS for your NAS from https://www.plex.tv/media-server-downloads/?cat=nas&plat=asustor
- open the NAS admin interface and go to the app center to manually install that app package
