I'm attempting to change the show art for my podcast. I uploaded the new image to my SoundCloud channel (with a different file name to the original), and after pinging Feedburner it showed the updated version there. However, it is not updating on iTunes and is therefore still the old version for the iTunes Store, Podcasting apps etc.

iTunes page: https://itunes.apple.com/podcast/goplaythat/id960695374
Old art: darker blue, gradient
New art: lighter blue, solid color
Do you have any ideas for what may be the cause of this issue? Any advice? I can try enquiring on the Apple side too but wanted to eliminate this being an issue on this end.
