Podcast episodes missing in iTunes Store
There have been a number of cases of podcast episodes missing from the Store - sometimes all of them - even though they all appear when subscribing (indicating that the feed is apparently OK).
If you run into this problem, go to Podcasts Connect, sign in, select your podcast and click 'Refresh Feed'. This has worked fairly quickly for several people. If it doesn't work, contact Support and ask for a re-index: that may solve it. Go to https://itunespartner.apple.com/en/podcasts/overview and click the 'Contact Us' link at the bottom of the page.
