I like to know, why it has to be so, that The navigation functionality is still accessible, when you turn off arrows, and you can go back and forward between questions?
Some, who tested my survey, went accidentally back, when they used mobile device. And they did not know, what was happened. It is very cracy.
My survey needed to be like, that you can not go back and change answers, but now this is not possible
That you hide the Navigation arrows, does not help at all.
That is not only thing, what does not work properly.
Other is example that ok-button: you do not need to press it, when you answer questions, which you have to select only one answer.
