Some time ago, I had an issue with Clean Business Pro on mobile devices. The issue was the masthead partially covering the slider/header images. You provided some CSS to solve the problem. I have since realized the real problem is the opacity on the masthead is not operating the same on mobile devices compared to desktops. The masthead remains solid while scrolled up, rather than transparent as seen on a desktop. You can clearly see this effect on your own demo page for Clean Business Pro. For example, if you review the demo for your NepalBuzz product, you will see it operates correctly on both desktop and mobile devices.
I would appreciate if this could be corrected on a future update.
