Apple Podcasts episode not publishing; RSS feed URL reverts

Can't Publish Episode via Lisbyn

I first tried publishing the first episode of my fourth season Tuesday, November 11 via Lisbyn. It accidentally published twice and although the episode appeared available on Apple Podcasts, I couldn't hear the audio/ hit play on the player, so I deleted both episodes and republished. The episode never reappeared on Apple Podcasts. So I tried deleting the episode and republishing it the evening of Thursday, November 13. It still hasn't appeared on Apple Podcast (all the while it's been on Spotify). I have been in touch with Lisbyn who recommended I change the file size of the show's logo, select whether or not I use 3rd party content and change the RSS feed. They said "The format change for the RSS Feed url is expected as our system is using a new method to generate RSS Feeds." I have done these things and have now changed the rss feed url twice on Apple Podcast Connect, only for the URL to revert back to the original without my doing so. Any ideas why the episode still hasn't published? I've reached out to to Apple Support but still haven't heard back. Desperately hoping to get this season up ASAP.
