Same issue here, however it seems that since plex implemented the .plexmatch for series feature ( release notes ) plex parser does not recognise anything except what is documented in https://support.plex.tv/articles/naming-and-organizing-your-tv-show-files/
ALL of my files have the following formats: Series Name [1x01] - Ep name or Series Name - 2050-02-02 - Ep Name depending on need.
After the update only the second example I gave was getting parsed and added (as they are coincidentally the same as documented in the section Date-Based Television Shows ).
When I changed some of the newer additions to my file server to the format specified in the second link provided, i.e. Series Name s01e01 - Ep name they all got parsed.
I checked logs and no errors exist, in fact when it gets to a folder with new additions it will say in the logs that it found X amount of new files not in the database and starts parsing them. Only the ones with the changed naming structure get added.
@ChuckPa I have ran the database optimization and checked logs (before after and during) for any errors or warnings (and I get warnings about slow queries, but I’m 99% sure that has something to do with my bad vhdd configuration that i have been too lazy to fix), and I have no errors.
