3. Click the "X" next to the show or movie you want to delete. The line item will turn grey and you'll need to click a link that says "Remove Series?" This removes the selected item from both the “Viewing Activity” and “Continue Watching” areas on your account.
Word of warning: If you're trying to delete a single episode because you got an episode ahead of someone you watch a show with, it doesn't work like that (though, you can stop Netflix cheating with these rings). By deleting one episode, you delete the entire viewing history for that show. If you're looking to delete evidence that you just binge-watched Fuller House, well, then you don't have to delete 13 separate episodes. Delete one episode and all the evidence will evaporate.
