I have been successfully using PLEX server on OSX (mac mini) for a number of years.
My media library is hosted on a ubuntu server and I use AFP to connect Plex server and Ubuntu server.
New TV shows successfully provisioned and added using Sickrage including post processing notification.
I also run plex on ATV4
Recently some series in a show have been dropped by Plex server, I have tried may possible solutions and not have been successful.
The interim solution is to use Plex edit and refresh a show, this the episodes are back in the library.
Note i done do a nightly refresh of my PLEX library
has anyone come across this problem and how did you fix
