I use an excel spreadsheet in OneDrive as my app's data source. The PowerApps has generated a nice looking functional app for me. Then I decided to add a few more columns in the spreadsheet to capture data. In the spreadsheet, these columns only has headings and no data in the actual columns.
Once I updated the spreadsheet and refreshed the data source in the PowerApps Studio, I cannot find anywhere to add the extra data card to reference back to these new columns.
I right click the Screen but there is no option to add data card.
