Are you sure there are objects in that list? Maybe you need to create some data on the web interface first, or add a “create” button on the mobile app.
To troubleshoot: Add some static text to the page to ensure that your changes are actually displaying on the phone, then double-check your data. You should also set the list view’s pull-down action to “synchronize” so that you can re-sync your data.
I hate to say it. But I rebooted my phone and it seemed to work properly. Not sure if the app was not refreshing on my phone properly. I’ll update this feed again when I run into this and see if that is the fix.
