If you change certain things on your podcast, it is necessary to manually update the feed on Apple Podcasts so that your changes are visible before you publish a new episode. 

This is the case, for example, if you change the cover image or change the category. How to give the feed a little push, we explain here: 

• Sign in to Apple Podcasts with your account.
• From the My Podcasts menu, select the podcast you want to update.
• Here you will find the note "Update feed" at the bottom. Just click on it and 24 hours later your change will be visible.
