Q: my podcast from last week in not showing up in my Itunes store

Several people have complained recently that the Store is being slow to update so it's possible that you've been affected by the same thing. Of course it might be something else, like some sort of technical problem with your feed, but obviously I can't diagnose that without being told its URL.

I have a similar question.

I have created a new podcast and have uploaded 2 episodes on the same day (podcast rss feed - http://simplecast.com/podcasts/1769/rss & podcast page - https://thesea-townpodcast.simplecast.fm/episodes) but when iTunes picked up the feed, only the most recent one posted (iTunes page - https://itunes.apple.com/us/podcast/the-sea-town-podcast/id1089833365?mt=2),missing one episode entirely and now they are going to be out of order.

How do I get iTunes to pick-up the other episode?

Can I only post 1 podcast per day or expect to experience this again?         

When you have a problem it's better to start your own thread - sometimes it can get confusing when people add on. The OP here may well come back and then we'll have interleaved answers.

Episode 2 is in the feed and appears for subscribers, so it looks as if this is another Store glitch - several people have reported slowness in updating. You should certainly be able to post more than one episode a day (though it's better not to as subscribers may miss one for automatic download). This certainly looks like a version of the same Store problem and there isn't really anything you can do at your end. You could report the problem to Support: go to https://itunespartner.apple.com/en/podcasts/overview and click the 'Contact Us' link at the bottom of the page
