I understand right now there are two HUGE bugs affected the entire application. They are:
#1) Some users can’t save their quiz choices.
#2) Some users have weird quiz choices added to their questions after saving (a field with a ’1′ is added)
#3) Some users have questions and choices that are not in their quizzes being displayed in their quiz
We are working really hard to rectify these issues, and am really, truly sorry for all these inconveniences caused!
Do feel free to mail support at email@example.com
We will update as soon as the bugs are fixed!
