I am modifying a SharePoint form in PowerApps, and I'm trying to populate a text field based on whether or not the Created By field (from SharePoint) is populated. Essentially I'm trying to set a field upon submission from a button i created. It doesn't populate the form in SP, even though it works in preview mode. So is there a way I can have a text label display "Submitted" if Created By contains a value? If it doesn't, it can just be blank. Created By gets populated upon submission, so I'm trying to reference it.
