It was working fine for a couple of years, noticed it wasn’t working properly after the last update, tried re-installing and now Plex doesn’t recognise it at all. It’s not ideal anyway to be honest… I’m happy to switch to proper naming instead, but when Plex still doesn’t allow any kind of manual matching for episodes it gets really frustrating.
Thanks for Plex Dance suggestion anyway, haven’t tried that so will give it a go!
