If you're paying, there's probably a way to get a RSS feed for paid subscribers. If you can't find it, maybe email tech support?

This is how all the podcasts I donate to work (they offer ad-free feeds, bonus episodes, etc, usually with some url like https://rss.podcastsite.com/show?token=<random code>, and then in my podcast app, it either says "Some show - Paid feed", or sometimes "Some show - your name's feed".
