My family sharing is hacked
I can’t remove a bogus family member, or manage any of my family members for that matter
iPhone 11 Pro, iOS 15
If the “bogus” family member is attached and can’t be moved, I’m thinking possible child account https://support.apple.com/guide/iphone/add-or-remove-family-sharing-members-iph8f958ab3f/15.0/ios/15.0
if you have problems with management you could try removing the adult accounts (including teens) but could just be the screen time settings https://support.apple.com/guide/iphone/set-up-screen-time-for-a-family-member-iph7f15d92dd/15.0/ios/15.0
