All of our subscriber-only podcasts and bonus segments can be listened to on-demand in the articles published alongside each new podcast episode. If you want these to show up automatically in your favorite podcasting app, you can use your private RSS feed. Find this subscriber-only URL under Podcast Settings on your My Settings page and enter it into iTunes or any other podcast app to automatically check each day for new episodes.
If you are having trouble adding a podcast URL to your podcast app, check out this article for step-by-step instructions with a variety of apps: https://medium.com/@joshmuccio/how-to-manually-add-a-rss-feed-to-your-podcast-app-on-desktop-ios-android-478d197a3770. Note that as of July 2022, Spotify, Stitcher, and iHeartRadio do not support adding podcasts by URL (the prior article has a great selection of alternatives though).
