On most linux distros – Do not use /media as the parent directory.
Gnome’s Nautilus and automounter claim exclusive use / ownership.
By default, they define exclusive access for your username ONLY.
Username plex will not be able to see anything in there.
The solution is to define the mount point(s) in /etc/fstab
and choose another place to mount.
Please review:
Once you’ve moved the mount point, you’ll be able to change the ownership and permissions back to normal.
