Episode specific picture not appearing for podcast

Hi - I publish a podcast through podbean - and podbean distributes the podcast to all the big podcaster guys! Everything is all OK - however, on the episode (published yesterday) - the episode specific picture is not there (although its there on Spotify, and other platforms). I know, it's only a minor thing, but it's really frustrating me!!

The feed for the podcast is https://podcasts.apple.com/us/podcast/you-bet-podcast/id1848705254
