Very often this will get ‘merged’ with another movie.
This in turn is often caused by improper file names or if you have several files with identical embedded ‘title’ meta data.
Try to enable the ‘duplicates’ filter in your library. Then inspect the Plex media info of those items, which have a small blue number in the upper, left corner of their poster.
You might find your newly added file among them.
Here is a procedure which I recommend to battle the influence of embedded meta data:
Go to
- Settings - Server - Agents - Shows - TheTVDB
In there, grab the line ‘Local Media Assets’ with your mouse and drag it downwards, so it ends up being at the bottom of the stack of active agents.
Repeat the same under
- Settings - Server - Agents - Shows - TheMovieDatabase
- Settings - Server - Agents - Movies - Plex Movie
- Settings - Server - Agents - Movies - TheMovieDatabase
Make sure your files are named according to the official Plex guidelines

I recommend the ‘one subfolder per-movie’ approach.
After doing the above, perform the Plex Dance with the movie in question.
Perhaps “dance” also the movie under which poster you found your new file.
