I have been trying to add some TV episode extras to my Plex server. According to this article, I added the files as follows:

Show
├── Show.S01
│   ├── S01E01.Title.mkv
│   ├── S01E01.Title-behindthescenes.mkv

I noticed that the extra could be properly parsed and shown in the iOS player, under the episode’s “Trailers & Extras” section, but on macOS and Web players, there are no “Extras” section under single episodes at all. Show-level extras (that put in subfolders) work fine.
