I realize there are probably a million posts on this topic, I've looked through a few already on this site. I'm a novice user, I've never backed thigs up. Today, I just got back to using Lightroom classic after several months and it updated the catalog. Now my presets are missing. I tried searching through the Lightroom files manually to find the presets, nothing there except for the defaults.
This is extremely frustrating because I've been using those presets for years.
