Error adding another iPhone user as account recovery contact - "You can only add people who are using an Apple device"
Trying to add my husband as account recovery contact. Getting error message that says, "You can only add people who are using an Apple device." He's on iPhone 13 and so am I. What is the fix for this? We've walked through the article on setting up account recovery and verified that he meets all of the criteria (Apple ID, 2FA, etc.)
iPhone 13, iOS 15
