Hi
I'm just about to launch a couple experiments which will be done over the internet and on an ipad although the launch page is presented in landscape once the actual task starts the survey is presented only in portrait and is not responsive to changes in orientation or the size of the screen. Also it's not possible to scroll across the screen on either an ipad and laptop, so some response options are not visible.  Is there an way to fix this?
Many thanks in advance
Jenny

Not sure I understand the question -- and it's hard to tell what exactly you are referring to without some concrete examples (code, screenshots) -- but you can force a certain orientation under iOS via the canvas settings.
