we registered some problems from participants of our actual survey as they got kicked out (without any error message) by hitting the next button - on different pages - of the survey before submitting the survey on the last page.
Unfortunately there is no way to ask our participants what exactly happened but we got feedback from approx. 30 participants which got kicked out (and for sure some more which did not give us feedback) and I am quite sure it is not only a problem with the systems of the users.
Did someone else have similar problems? Is it possible that this happens when there are too many participants completing a survey at the same time? Or is it possible that they are kicked out when someone enters the admin site of LimeSurvey and selects the ongoing survey (but does not change anything there)?
Any hint would be helpful.
