Go to each of your shared folders containing media;

  1. Control Panel - Shared Folders
  2. EDIT the shared folder
  3. Permissions tab
  4. Change “Local Users” → “System Internal User”
  5. Grant “PlexMediaServer” (the application) permission to read/write.
  6. Save

Control Panel - Shared Folders - Video share - Action

Look at “Convert to Windows ACL”

If available - click it. It will repair the ACLs

After it repairs, assign permissions again.

The “video” shared folder is owned by DSM.

finally I did it. not by repairing ACL, but by enabling “Advanced Share Permissions”
