Moving pieces by symbolic links is A) Dangerous and B) not supported.
This is probably contributing to the problem.
The proper way to move (relocate) your Plex metadata is here:
If you want to start over, I recommend:
-
Create the target directory in the new location to hold the metadata.
a. Make certain the new directory is owned byplex:plex
. -
sudo systemctl edit plexmediaserver
as instructed in the above How To -
sudo systemctl daemon-reload
to update the system’s knowledge of the config change. -
Open https://app.plex.tv/desktop
a. Plex/web will load
b. Settings - Authorized Devices (Upper left corner) - Server (dropdown)
c. REMOVE the server you’re starting over
d. Close the browser window -
Start Plex and setup again as new.
