National Casino - Poor Windows phone compatibility
Case summary
They say they work on mobile compatibility a lot yet I tried to use a website with my Windows phone and the whole experience was weird. When I tried to scroll down, I was always redirected to the top of page. Impossible to use. They should work on compatibility with other operating systems too, not just Android and iOS.
