I picked the option to manually order the music albums within a collection. I can drag the album to whichever order I want, but when I go out of the collection and go back in, the order is changed randomly… This happens on the desktop app and web.
All my collection that were created a couple days ago work fine, but the new ones I create all have this issue. My PlexPass ended in the meantime, maybe this has something to do with it?
