ITunes is not updating my podcast description

Question

Hello community,
I'm the admin for the Open Society Foundations podcast feed, and iTunes has not updated the podcast description or image and I can't figure out why not.  Any advice or assistance appreciated.  This is the feed with the current description: http://feeds.feedburner.com/OpenSocietyInstitutePodcast.  iTunes is updating all episodes, it's just not updating the description, which is in the xml file as:
<itunes:summary>The Open Society Foundations work to build vibrant and tolerant democracies whose governments are accountable to their citizens. To achieve this mission, the Foundations seek to shape public policies that assure greater fairness in political, legal, and economic systems and safeguard fundamental rights. On a local level, the Open Society Foundations implement a range of initiatives to advance justice, education, public health, and independent media. At the same time, we build alliances across borders and continents on issues such as corruption and freedom of information. The Foundations place a high priority on protecting and improving the lives of people in marginalized communities.</itunes:summary>

I've read through other threads here and I believe I've confirmed that iTunes is pointing to the correct feed, and that I'm using the right tags.  But, clearly I'm doing something wrong -- just can't figure out what.
Many thanks!

Although on subscribing iTunes is showing the contents of the 'description' tag (I thought it wasn't before. but I could be wrong) the 'itunes:subtitle' and 'itunes:summary' tags are still empty. If you've made the changes, have you uploaded the changed feed?
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 mention 'new episodes' but there is only one episode in the feed.
