New form layout, iphone 6

Hi, 

I've just created a new form using your new layout design. However, my friend had issues on the iphone 6 on the first page which wouldn't scroll down unless he found a very particular spot on the phone. 

Are you able to help?

Thanks

I tested out the form on iphone and other mobile devices, and it was working fine. Can you please provide a screenshot of the problem.
