I have a lot of apps bought for my old iPad 2. Recently I got a new iPad mini, and put on it some of the apps (using the same Apple Id). When I tried to buy a new app from my iPad mini, I was asked 2 security questions for the answers I forgot (it seems to me, from my note made 2 years ago, that there was only one such a question, different however than the current ones). Anyway, now I cannot make any new purchase from iPad mini (only from the old Ipad 2, and then to get it on my mini). Impossible to solve the issue by going to iforgot.apple.com since it keeps asking the same questions I have no answers to. Any suggestion what to do in order to enable purchases on my iPad mini?
