Q: change family organizer to other family member

Hello realoldschool,

I understand that you would like to change who is in charge of your current Family Sharing group. With Family Sharing, whoever starts it will always be in charge of that group. An option is available to set up a parent/guardian if you are needing someone else to approve apps. If you are wanting someone else to be fulling in charge to be that Organizer role, everyone one will need to leave Family Sharing. Once that is done, the person you want in charge will need to send out the Family Sharing invitations. Take a look at the articles below for more details.
