Had to revert to our former solution since the one above kept refreshing the page too quickly and made the form look broken.
I ended up placing a rule on a Yes/No dsropdown field that our On Creation workflow would update as its last step. On Form load, if this field was still “No,” the rule would hide the form tab and show a tab with some HTML and a loading .gif. This custom refresh function reloads the page after 25 seconds.
function customReloadPage(){
setTimeout("window.open(self.location, '_self');", 25000);
}
