Yes, of course I know how to add a Gravity Form to the Popup with Ajax, the issue is the shortcode works on the Visual Builder and the form is visible. Once I save and exit the visual builder on every browser it basically becomes invisible. I use the following code to FORCE the form to show on about most browsers:
let someGfJs = $(".gravity-theme, .gf_browser_chrome, .gf_browser_unknown");
someGfJs.attr("style", "");
The is a band aid however and not a fix. I will email with screen shots etc.
