I have created an app using Ovi App Wizarad. The app is SJMW Toons - http://store.ovi.com/content/78906.
The app was created using the rss feed from http://mobtouch.wordpress.com/category/cartoons/feed/. When the feed is viewed directly from any browser, latest images are displayed.
When the app or ovi appwizard link (http://oviappwizard.com/mip/plus/list.jsp?id=259591) is viewed, older images are displayed. It would be good if the cache is cleared every day or an option is provided in the wizard to cache or not.
