Most podcast apps allow users to add private RSS feeds, but there are a few widely used apps that haven't added that feature yet. For example, Spotify doesn't support adding a private RSS feed at the moment, so you can't listen to bonus content on those platforms. You can find a list of instructions for adding the bonus content feed to your podcast app towards the bottom of the page at maximumfun.org/boco. If you aren't able to get bonus content on your app, you can always stream or download it from that page! (Plus that page has some extras like videos and digital art that don't show up in the RSS feed, so it's fun to pop in there every now and then for that stuff even if you do use an app.)
