About adding new content for your Live app, you can use Resource Sync feature created by our developers.
Once your application is Ready For Sale in the App Store you will have possibility to synchronize resources (images, sounds, html files, etc.) with app without releasing a new app version. To choose what files do you want to be sync go to your app’s Dashboard -> Edit Pages -> Resource Manager.
The check-box on the far right of the appeared table represents the sync feature state of the file (pages).
When user taps REFRESH button in the top left corner a panel appears. Selecting Sync will update files from the server.
Note: sync option is enabled by default for app.xml.
Note: just files set as SYNC in Resource Manager will be updated.
If sync feature is not needed you can disable it in the Submission Process.
