Having a similar problem – iTunes showing feed but no episodes – but it seems that I definitely have an episode up and playing audio at the WordPress end of things.
episode wp link: https://www.jackdean.co.uk/?podcast=1-camelot
Itunes link: https://itunes.apple.com/gb/podcast/fake-town-fables/id1114881723?mt=2
Can you please help?
Thanks
