RSS Feeds don't work

When creating the app inside ZipApp, you can import RSS feeds into groups, however this only appears to work at the point you download the app.  Once the app is deployed the RSS feeds are actually just static content, so any new articles published to an RSS feed does not show up.  E.g. I configured an RSS feed to point to a wordpress blog with one post ('Test1') then I downloaded the app and then went back to wordpress and created a new post ('Test2') however when running the app it only shows 'Test1' and not 'Test2'.  Have created more posts and same issue, only shows 'Test1'.  Upon searching Find in All Files in Visual Studio for RSS, only 2 instances were found - one was a case "RSS" which is I believe for formatting RSS data as an article, and the other was a mention of RSS in one of my descriptions.  Thanks for all work on the app btw, appreciated! :-)
