Yeah I have a couple ntfs drives I didn't want to clear completely and start over with so I just created a directory, mounted them there and gave permissions for whatever the username is that is in jellyfin (plex in this case).

Quick work around. During a fresh install I just remount, give permissions and map them as a library and all is well. As with most things, doing it while being shit faced drunk doesn't make it quicker though. That only works for cutting hair
