I already submitted a ticket about this, but I tried to enter a response in the other section of one of the questions, and the survey just decided to move to the next page on it's own. It doesn't let you change answers so I tried to refresh the page to redo the survey as it was not submitted yet. I accidentally made another error and tried to do the same thing again, then it said the survey was submitted with it saying only 37% was done before then.
I'm not sure how that could even happen, but be careful with this survey because it seems kinda unstable. They also should really let use change answers from previous questions, because humans make mistakes.
