Q: Problem with posting my podcast's audios

In fact the Store is showing only three episodes, from 25th and 28th March. There are seven more episodes in the feed, posted only today in the last couple of hours: there's nothing unusual about their not showing yet.

When you add a new episode to your feed and upload it, it appears immediately for subscribers because their iTunes application reads the feed directly and the Store is not involved.

However because of the huge number of podcasts in the Store (thousands) the Store caches the feed and checks it for updates periodically. For this reason it usually takes 1-2 days for new episodes to appear in the Store: sometimes it can be less, and occasionally the whole process seems to get stuck and it can take several days.

You should check your feed by subscribing, either from the Store page or manually from the 'Advanced' menu in iTunes, to see that your new episodes are there. If not, then you have an error of some sort (such as a duplicated 'guid' tag). If all your episodes appear when subscribing then the Store should catch up after a bit.

All your episodes appear when subscribing in iTunes: but if you post a number of them all on one day then subscribers are likely to automatically download only the most recent at the time their iTunes checks the feed. It's better to stick to one episode a day unless you are sure your subscribers will take the trouble to manually download the other episodes.
