Libsyn has worked with Apple to identify how we could get our user’s show artwork updated more reliably.  As a result of working with Apple we believe that we have identified a way that can get Apple Podcasts to refresh most of the artwork that was “stuck” or outdated.  Many of the shows that were originally reported as having stuck artwork are now showing up correctly in Apple Podcasts.  If your show still appears stuck, please be patient.  Apple Podcasts servers take some time to refresh the images that they cache and these changes are still trickling out.  Your artwork should refresh shortly, so keep checking back regularly.
