Getting Playback Error after moving media

[jwlp]

Server Version#:1.20.4.3517
Player Version#:4.46.2

After getting advise to not store media in the Multimedia QNAP NAS folder, I have moved all my media to a new unique folder called PLEX Media.

As a result, I am getting the following Playback error:

What do I need to do to resolve this issue?

Thanks!

I followed @beckfield’s good advice, " You have to edit the library to point to the new location, then run ‘Scan Library Files’ so Plex knows where they are". and this resolved this issue.

(Sorry for this duplicate thread. Being new, I had lost the earlier post but now understand how to find them.)

Unfortunately, I now have a new issue related to loading new albums to our Plex QNAP Server (one Whitney album and three Reba albums)

Reviewing the Plex Music folder, I see all four of these albums. However, unfortunately, I only see two of the Reba albums and not the Whitney album via the PLEX.

Any advise regarding how I can troubleshoot this issue further?

Thanks!
