Just tried to install a free app through the app store on IOS 7 , Iphone 5, it's prompting me to enter 3 security questions to "Improve Security" problem is ... I can't even select a security question... I've tried tapping on the "choose questions" field and nothing pops up, i've tried tap and hold, tap on the arrow, even swipe .. I just can't seem to make the security questions pop up. I tried just entering the 3 questions without selecting the questions, press "Done" .. nothings happens. Any suggestion?
