Scrolling disabled on iOS

[thowitz]

Hi, I've had a problem for a while now where when scrolling to the top limit of my website on an iOS device, it bounces back, I have a navbar that hides on scroll at the top, so when you scroll past the top boundary, the bouncing back makes the website think it's scrolling down, so the navbar hides. I tried to implement I no bounce, but it doesn't fix the problem, in fact it makes it worse, the user isn't able to scroll unless they zoom in or out, I was wondering if anyone could help me.
