With the release of AppleMusic and the Family Package I decided to add my 3 children and partner to my Family Sharing. I noticed that the 8 year old was showing as an adult and decided to try and change her age. So I followed the following steps.... I Logged on to her appleid.apple.com and changed her date of birth. It then sent me an email which I clicked the link to approve request to turn her from an adult to a child. I was then prompted to verify my ID and iTunes account by entering my Credit Card info. Once this was done, I would have expected to go to another screen to complete the processes... But nothing happened... so I repeated the processes... over and over again... The Result... She is still an Adult... And I now have 11 pending payments (which I'm sure will be refunded) but it's left me out of pocket in the mean time!
