Issue with Previewing - Both Web and Mobile

New to Appgyver - Need Some Help here!! On the designer, the information is present on each of the pages extracted from the (Airtable) REST API, but on preview, nothing is displayed, neither web nor mobile previews

Hi,

Are you sure the REST API is working and you are able to retrieve the data? Do you see any errors in the developer console in the web preview? Open the web preview, open developer console by Command+Option+J or Control+Shift+J , reload the page, and see if there’s any errors about the data retrieving.
