PageFly Landing Page Builder

Customer support deserves 5 stars, they are really helpful. Thythy did a nice job with recommendations for my landing page.
The only issues I have experienced until now, are related to how the app works along others. I use Up Cart, and when you have a direct buy button, the product doesn't appear immediately on the cart, until the 2 or 3d time. Other issue is the page loading speed while editing, it could be better, I have to refresh continuously.
