We have been receiving reports since Friday evening of issues submitting to Apple Podcasts and also with delays in shows updating in the Apple Podcasts store. We have seen similar reports from feeds hosted with Libsyn, as well as feeds from other sources.
We have reached out to Apple Podcasts and they are currently investigating. We will post updates as they are received.
UPDATE 7/13/2015 9:40am: We have heard back from our contacts at Apple Podcasts, they are still investigating but have asked that those having trouble with submissions retry their submission. If you continue to have trouble, please contact [email protected]
UPDATE 7/13/2015 4:45pm: We have heard from many producers that content is again properly updating in the store and submissions are going through. Thank you for your patience in this matter.
