Like many others, I created my kids their own AppleID a long time ago using my birthdate so that they could have iCloud accounts for backing up their devices and not using up my storage. But now that iOS8 is GM (yes I am a developer), I loaded it up on their devices hoping to use the family sharing and "ask to buy" feature, however I can't seem to be able to change their birthdate to an age younger than 13 (they are 7 and 10). Has anyone been able to get this changed successfully? Also, I haven't been able to get the "Ask to buy" feature working yet either. It keeps asking for a credit card on their devices despite showing in my "organizer" account the proper CC that should be used for everyone on the account.
