I've set two question in version 2.50 and version 3.17.0
dynamic slider and array
version2.50
version3.17.0
When I use smart phone to answer these two questions,
in version 2.50, the array question will be convert to like dropdown question, and dynamic slider question is easily to slide.
But in version 3.17, when I use smartphone, the screen is to small, and hard to choose answer, the respondent need to zoom in the screen then answer the question
