You may delete some episodes from your podcast's RSS feed, but find that those episodes are still on Listen Notes. In this case, there are two ways to get those episodes deleted from Listen Notes.
Approach 1: You can simply email us ([email protected]) with the Listen Notes url of your podcast. We'll do a full RSS refresh to sync up and eventually delete those episodes.
Approach 2: If you've claimed your podcast page on Listen Notes (How to claim your podcast), you can click "Refresh RSS" button on your podcast's manage page to do a full refresh (where's the manage page).
