What are you still missing?
The issue from back in May where clicking on a folder didn’t actually open it has long been fixed (according to the release announcements, this should have been fixed with Plex for iOS 6.12.1). Just re-tested this on Plex for iOS 7.3 and it’s working just fine.
Edit: as pointed out by Hitsville and in many other threads… it’s not gone or MIA.
Folders is not a “view” (like grid view, summary view, list view) – folders is part of the “display mode” of your library where you can pick what aspect of your media is displayed:
For movies:
- Movies
- Folders
For tv shows:
- Shows
- Seasons
- Episodes
- Folders
For music:
- Artists
- Albums
- Tracks
- Folders
