Unable to detect a replaced file

[JBSDS]

Hello,
I have a problem when updating an existing file (alreday scanned), when a file has already been scanned, that I update it with a new version, Plex Autoscan scans again the folder where the file is located but it does not detect the modification so it does not replace the information of the file and if i deleted the previous file i can't have the new file. I tried to make a plex dance (https://forums.plex.tv/t/the-plex-dance/197064) and to pass to the PLEX user with the command "chown" but nothing works.
Thanks you for your help.
