Why would one run this add-on? Isn't the built-in plex scans good enough to detect file system changes? Mine reacts pretty quickly (within a minute or so).
With cloud mounted remotes plex doesn't detect changes on that so you either have to trigger a full library scan or you media doesn't get updated.
With Autoscan apps it trigers specific scan locations. So no need to scan the whole library. It only scans specific folders where the new content was added. This help reduce api calls to cloud remotes.
