Oh, that’s right, there’s a problem that was reported last month.
Plex doesn’t read in the whole list when you open a large library. It only loads a few at a time, so you’re not waiting forever to open the library. If you notice, when you scroll down the page, new entries get loaded up as you scroll.
In order for the mass selection feature to work with a long list, you have to scroll through the pages slowly enough that Plex has a chance to read in the whole list. Once it has read the whole list, you’ll be able to do what I’ve been telling you.
Hopefully that will get fixed, but for now that’s what we’ve got.
