Whether your site is responsive or designed to be generally desktop-only, regular surveys will not display on mobile devices. You will need to create a mobile survey if you'd like to get feedback from your mobile visitors.
The reason for this is due to the difference in user experience. Mobile and desktop environments are quite different in terms of screen size, readability and the amount and type of content that can be viewed. Visitors have different expectations for the same website on each device. We created the mobile survey add-on that keeps these limitations and expectations in mind.
