Plex with rclone mount - possible to auto update/partial scan?

Awesome stuff @Stokkes However, I’m getting a crash and permission error when the program detects the change:

Permissions look fine though /var/lib/plexmediaserver/Library/Application Support/Plex Media Server:

My setup passes all the requirements, I think. rclone mount is at /home/omanko/plex/mount, cache is at /home/omanko/plex/cache/gbcache. File structure is exactly the same. PMS is not in a docker.

Is this due to the fact I’m not running as plex user? Do I just do sudo chown -R user:plex /var/lib/plexmediaserver
