Plex scanner can't be chosen

Pulling my hair out…

I am not getting proper metadata after moving the location of a library. As the item name it is putting the path in the file system to where the item is, not the expected metadata and not even the file name itself.

So…I wandered over to the wiki to refresh my memory on how all that works. I was expecting to see “Plex Movie” as the agent for that library. It wasn’t. It was “Plex Movie Scanner”. OK, so I’ll just switch it. Nope. I get the dreaded “Changes can’t be saved” message.

I am doing all this with a small library on purpose. It only has 12 items in it, but I am having this issue on multiple libraries. If I delete the library entirely, do the Plex dance and create a new library (tried with both same name and new name) with the same outcome. Not only can I not change the scanner, but I continue to get nothing but the folder path as the description. HOWEVER, if I delete the library entirely and recreate it, once it starts to scan it does briefly show the correct/actual file name. By the time the library is done updating it all go to the folder name as the title…

I have also rebooted the Win10 Plex server multiple times to no avail. It is starting to sound something like this SSL issue that broke the YouTube scanner months ago…

[REL] YouTube Metadata Agent

Based on a seemingly unrelated topic here: A user fixed their issue by rolling back to build 6868. That was a few builds backwards so I tried each older build until my metadata started working again. Turned out 6868 is the latest one that actually works with the agent. The “breakage” is obviously related to the later server builds and it is apparently creating other issues like the UNC path problem in that thread, but don’t know if it’s something that the Plex folks are actually working on o…

…which was subsequently fixed with a Plex server update. That got me thinking maybe I need to roll back a version since an update came out a few days ago. Rolled it back to v 1.32.5.7318. No difference.

I’m kind of scratching my head here…

EDIT: the icing on the cake: if I choose a single media item and choose “Fix Match” it almost immediately matches properly. If I click on the title it thinks for a few seconds, but still displays the folder path only…

This morning I try to update my metadata and it WORKS this morning. I did nothing more. The server did not show any activity, but it worked properly updating metadata on one library.

On THIS library I can make scanner/agent changes successfully and did so. However, I tired another “broken” library and it did not let me giving me the dreaded “changes can not be saved” message.

Can someone explain if there is a background process I don’t have visibility to that is taking place here and forcing me to wait XX time before changes can be made? I’m going to try another library in a little while, but this is bizarre to me.

Thanks!
