I swear Plex had this feature ages ago and then one day it disappeared. The shuffle option is awful because no matter how many hundred of episodes a series may have, Plex only grabs the tiniest handful of shows from a particular show to cycle through. If Plex had the option to only shuffle shows that are unwatched, my life would be so much better, along with others’, I’m sure.
From a similar suggestion that was posted a few days ago… please check out the mentioned approach on how to use a custom playlist/collection to achieve shuffling only unwatched episodes. Similarly I’ve linked an older existing suggestion in that thread.
I’ll therefore close this thread as a duplicate.
2024 clean-up:
- available option to use smart collection/playlist, filtering scope for unwatched episodes
- duplicate → Shuffle unwatched
