The latest episodes is 7th February and this appears when subscribing in iTunes - it's quite normal for new episodes to take a couple of days or so to appear in the Store so this should appear fairly soon.
I did notice that from 2 January on the media file names have a stop in them - this may not be a good idea. The only stop should be before the extension. It works OK in the iTunes application - it's evidently not causing a problem in the Store, but I don't know whether it might be that that has upset the Podcasts app. I don't have an iOS device so I can't check with this app.
I would suggest you rename and reupload these files to remove the stop in the filename, and amend the feed accordingly.
Thank you Roger.
But I think the problem still remains, I'm afraid.
Because when new subscribers subscribe - they get all the lastest episodes. But when a new episode is released the App will not update it. Very strange.
And my english isn't that great. Is a "stop" one like these : " . " ?
Thank you again.
