Turn off family sharing. And get Apple to stop turning it on
I just want to turn of family sharing. It’s grayed out
This is a volunteer user to user only forum. So be patient.
Have you read anything in this link to leave a family share group? --> Leave Family Sharing - Apple Support
Are you the organizer of the group?
Are you a minor who wishes to leave a group?
The more information you provide, the more likely someone may be able to help you.
