Preview does not update with saved database entries


I started with the “Date Night” app and have since edited it to make it my own. That said, whenever I submit a new “Date” to the app, it shows up under the list of my submissions on the Profile page, and in the database, but it does not show up on the main feed where all of the pre-populated data appears.

Has anyone else run into this? Do I need to be on a paid plan in order to test this functionality?
