If you're uncertain about what your show's RSS feed is, there are a couple ways to find it.
If that doesn't work, you should be able to find your show's feed in your podcast hosting platform's dashboard.
Here are few examples:
On the web, visit Settings > Distribution > Your RSS Feed
Visit Directories > RSS Feed
If you're still unable to find your show's RSS feed, reach out to our support team and let us know where your show is hosted and we'd be happy to help you find your show feed.
