Partial scan on changes isn't working

Server Version#: 1.19.3.2764
Unraid Version#: 6.8.3

As the title suggests, the partial scan when adding movies or tv shows is not working. I recently moved plex from a dedicated server to my new Unraid NAS and I am using the official plex docker image. Everything but this feature seems to be working. I’ve looked for the usual error messages concerning the inotify limit and even increased the number of max watches, to no affect.

Suggestions?

Still not functioning with the new version 1.19.3.2852
