Hello All,

I have 27" iMac 17,1 spec as follows,
i7 4GHz
32GB RAM
1TB SSD
AMD Radeon R9 M395X 4096MB

How do I change my kids account from Adult to Kids in iCloud Family Sharing?
by default I must have set them all up as Adults.

Do I need to ask Apple or is there a way to just amend?
I tried logging into each of their iCloud Accounts and changing their Date of Births to their actual Date of Births, it changes and saves but if I log back in it reverts.

Thanks,
