I've encountered an issue several times where my iPad or iPhone AppWorks application downloads my app, but somehow misses one of the javascript files. This causes the pages to display incorrectly and some of the functionality to fail. The only solution I've found is to either delete/download the AppWorks iOS app again, or to add a version of the app to the gateway so it forces the app to download the new version.
Are there any other solutions to for a particular device to re-download an app within AppWorks?
