On an iPad2, in the app store, I choose "productivity" category, tap on "Free" to get the Calculator ++ app, then tap "install app", then iPad home screen appears and the app's icon (badge?) appears as if it's going to install, then get prompt for Apple ID password, enter password, then get the NEW prompt appears "SECURITY INFO REQUIRED" (this never happened before) saying you have to confirm password and answer your security questions, then you can tap either cancel or SECURITY INFO. Tap SECURITY INFO, and get SECURITY INFO panel, and under heading SECURITY QUESTIONS are 6 rows alternating label QUESTION, ANSWER. Tap on QUESTION, and get the list of questions. Each of the 3 QUESTION boxes lists different but similar (more confusing) questions to choose from. Please let me know if this is not clear, I'm doing something wrong, or if you know a way around this onerous new restriction on usage.
