If you haven't claimed your podcast on Spotify yet, go to podcasters.spotify.com and create an account and claim your podcast.
If you have already claimed your podcast on Spotify in the past, simply login to your account and replace the old RSS feed with your now new podcast RSS feed.
If your podcast was previously distributed to Apple podcasts, that would mean you would have already made an account at iTunes connect. Simply sign in and update your old podcast RSS feed with your now new RSS feed.
You can simply login to your Apple Podcasts Connect account and update your podcast RSS feed field section with your now new Hubhopper RSS feed.
If you had not previously claimed your podcast on Apple podcasts, you can do so by following these steps:-
Once you've created a new Apple ID, you’ll need to authenticate it by signing in to any Apple services such as Apple Music, the App Store, or the iTunes Store and adding a valid payment method. No transaction will occur until you make one so you don't need to worry about it.
Once done, you can access your podcast on Apple podcasts. You will then need to update the RSS feed field section with your new Hubhopper RSS feed.
This will notify both platforms that you have a new RSS feed generated for the same podcast which you had previously distributed. This will allow both platforms to maintain your podcast exisitng subscribers and start passing accurate perofrmance data to your Hubhopper analytical dashboard.
