Updating Podcast Image (feed from Substack)

Hi! I updated my Substack podcast image about two weeks ago. It fits all the requirements for Apple's images (and is updated on all other platforms Spotify, etc), but it won't update on Apple Podcasts. Any ideas?

Here is the podcast - https://podcasts.apple.com/us/podcast/under-the-moon-gate-with-erin-bagwell/id1737604244
