My daughter saved up the funds to buy the iPod. Since getting it set up for her I've noticed she is able to get apps that contain some language I don't want her to see (a joke app). I went in and changed the ratings under restrictions, signed out if and back into the acct and even turned off the device but the app is still avail to download in the App Store. If you type in "jokes" it's the first one. How do I restrict apps like this?
