If completely removing all database files/settings/trace of plex will fix it, I’m okay to go through that, but I tried that back in March, and all that did was leave my entire library unmatched, and completely unable to match anything. The only fix was the downgrade back to 1.18.8.2527 I documented what I’ve previously done in this older thread. This was the same version that suddenly stopped working for me, with no other changes to my system or to my network.
I appreciate the work trouble shooting, but before I go nuclear, I’d like to have a little more confidence that it’ll work.
