Podcast artwork is correct ONLY when subscribed
My podcast rss feed is https://followingon.com/new-blog?format=rss
The image in the itunes:image tag is this link here (a nice updated logo that I want to keep, and it fits the requirements etc)
But when you look at the podcast on iTunes, you get the wrong, old logo. I updated it months ago - so it's not just a matter of waiting. To make things even weirder, the logo comes up correct ONLY when you subscribe to the show in the iPhone Podcasts app. If you search for the show it comes up wrong.
I have tried resubmitting the feed in Podcasts Connect, but I can't get it to validate again. Is there something wrong with my feed? Or is it an Apple issue?
