I am new to the Pi but have been successful in setting up my Pi as a Plex server. The only issue I have is updating my library when I add a new file or change the name of a file. I initially made a mistake and mislabel a movie so the wrong metadata was attached to it in Plex. I have corrected the file name but I can't get the library to update. I have the same problem with getting new movies to appear. How do I get it to update the library?
