Sorry for the wait, but we decided to push this out with the public release of 1.31.0.
The support article is here: https://support.plex.tv/articles/credits-detection/
The feature has been enabled for all Plex Pass users now running PMS 1.31.0 or greater. It may take a while for your server to pick up the feature change, if you don’t feel like waiting a server restart should kick it into gear.
Please create a new forum post to report issues going forward, as this thread will get locked now.
