I have a screen containing two forms each of which users are able to enter data. When submitting the form the entered information is submitted to a SharePoint list. Within the first form I have a button that opens a second screen where a gallery is displayed. Selecting an item within the gallery sets the default value of a field within the first form to the name of that item. Additionally details of that item or saved within the SharePoint list using the patch function.
This works exactly how I would expect it to and when accessing the app through either PowerApps Studio or PowerApps online editor the gallery has is populated with records.
When I access the app as an "app" the gallery is empty and when selecting just fills as "black".
The data source behind the gallery is Dynamics CRM where the tables contain around 6000 records.
