I have to App and it works fine but I am referring to when you go to the site via a URL. I am in the "Main" view for tasks and nothing scrolls, so I can only see those 15 or so tasks that show on the iPad screen.
Do you have the "Experimental Top-Fixed Scrolling" feature turned on in your account settings? If so, try doing a two-finger scroll on the iPad. This is one of the downsides to this experimental feature.
