Can't leave empty Apple Family nor Join my spouse's Apple Family despite removing all other members.
I am unable to leave an Apple Family even though I am the only account left and the organizer. I would like to join my wife's Apple Family Sharing where she already has everything set up, so I can manage my daughter's new iPad with her. When I hit the remove button, nothing happens. When I try to accept the invitation from my wife's Apple Family it tries to leave my Apple Family but then throws an error saying I cannot.
For context: I had to spend 2 hours on the phone with Apple support two weeks ago to remove my daughter's old Apple account from this family, and then wait a week and a half for it to finally be done. (We're using a different email for her on my wife's Apple Family now, and all that's working fine.) They said this would work now, but clearly it is not.
Thank you!
