You can delete individual episode downloads or you can delete all downloads at once:
Deleting certain episode downloads
1. In Settings > Offline Settings (or Download Settings): Make sure "Download Heard Episodes" is toggled OFF. It should be OFF by default.
2. Next, go to your Listen Later, Favorites or other playlist you want to delete episodes from.
– On Android, tap the three-dots next to an episode, then mark Heard.
– On iOS, long-press on the play button next to an episode to mark as Heard.
Now, all your Heard episodes are marked to be deleted the next time your playlist tries to download new episodes.
Note: You can manually pull to refresh on any playlist to delete now.
Deleting ALL downloads
1. In Settings > Offline Settings (or Download Settings): Scroll down. Tap the "Clear All Downloads" button.
