Website surveys can be displayed on all types of devices. By default, surveys are displayed both on desktop and mobile; however, you may decide to target either desktop or mobile devices.
To do that go to Survey settings > Who should see the survey? > Create new segment
From a menu of targeting conditions pick What device do they use? and choose the device you would like to target.
❗️Remember! You have to enable the segment to display the survey properly! Also, disable all segments which exclude each other.
