Apple Care One is not a family plan
Why do you market Apple Care One as a family plan when you cannot add your family members devices if they are associated with their own Apple ID, regardless if you have included them in your Apple "Family"? Even your team members at Apple stores claim it's a family plan. This is truly misleading. I cancelled the service. I hope I get a full refund of my initial payment.
