My podcast artwork hasn't update and I changed it 2 weeks ago...

So I recently changed the artwork for my podcast on Soundcloud, and it meets all the specs for iTunes (1400x1400), however it's been over 2 weeks and still this change hasn't reflected in iTunes.

The podcast lives here on Soundcloud: https://soundcloud.com/louderthanwordsjohnbonini

And is streamed here on iTunes: https://itunes.apple.com/us/podcast/louder-than-words-creative/id981162554?mt=2

Am I missing something?
