SOLVED: Blank Libraries

[RegP]

Found the solution. It was a permissions issue. I had to take the following steps and now Jellyfin can see the media in the new folder.

Open DSM Control Panel, Shared Folder

Edit Shared Folder, open "Permissions" tab and select "System internal user" view

Select either "Read only" on "Read/Write" for package user e.g. sc-jellyfin
