iCloud advanced data protection problem
I have an iCloud family plan. One of the ephors in the plan belongs to a family member who lives out of my house. All of the phones and Macs are updated to the latest OS but the device that is not in my house in not registering as updated. Therefore I can not turn on Advanced Data Protection.
Is there anything I can do or is this just a known problem?
thanks
