Tea and Whisk review for Prehook: Quiz Funnel Builder

I am surprised no one reported how buggy this app is. The first time I created a quiz, it won't show me any product recommendations. The second time, I created works fine. But as soon as I move around the questions, the problem started showing up again. It seems like you have to plan everything from the very start, anytime you want to make changes then the app starts acting weird. Am I really the only one that has these problems? I tried to contact developer, but haven't received any response yet.
