Screen Cutoff issues with IOS 6+

Hi,

My client has an IOS 6+ and he says he is only seeing 'half a screen'

Now when I load it up in the 6+ simulator (I don't have one) it kind of looks cut off. But when I scale down the simulator to 75%, it's not cut off.

It runs fine on my IPod, and fine in the standard Iphone 6 simulator, but not in the Iphone 6+ at 100%

My UI Canvas is set to scale at 0.5 width/height with a native resolution of 800 x 720.

Can anyone tell me what's happening here? How can I fix it so it doesn't run cutoff on an Iphone 6+?
