If you are using the free PopupAlly plugin, it is NOT possible to configure different responsive views.
This feature is provided in the Pro version. Most templates in the Pro version are equipped with mobile-friendly configurations. As a bonus, the Fluid templates in PopupAlly Pro allows you to add as many responsive views as you need.
PopupAlly Pro also includes email support and we’ll be happy to help you out with any further questions you may have. We have a 30-day money back guarantee on the plugin, so feel free to take it for a risk-free try. If you don’t like it for any reason, just let us know and we will refund your purchase.
