Can’t even see the right answers for the quizzes. The simulator is a complete waste of time if it doesn’t crash. 👎👎 **Developer response:** My first review, wahoo! And what a crushing one! I’m sorry you have experienced this. I didn’t have any reported crashes during testing, and I don’t see any crashes logged in the App Store reports so it’s hard to tell. Please, if you could go to your phone settings under ‘Privacy -> Analytics & Improvements -> Share with App Developers’— make sure that option is enabled, then run the application. When it crashes, it should send me crash report, and I can immediately look into what you might be experiencing and resolve this. Thanks for giving me a chance! -Greg ## Frequently asked questions about Backflow Buddy ### What is Backflow Buddy?
