Deleting a show can be done from the Show Edit screen. If you are certain that you wish to remove the show from Whooshkaa and make its contents not available externally any more (e.g. Apple Podcasts, Spotify, etc.), follow these steps.
Locate the show that you wish to delete and navigate to its overview screen. At the bottom of the screen, click the "Edit" button, which will take you to the Show Edit screen.
At the bottom of the edit form you will find the "Delete" button. Click this button to delete the show and confirm your action in the subsequent popup.
Please note that once a show is deleted, it cannot be undone.
