combine contacts with a family member
I can't seem to find how to combine or merge contacts with my wife, who is a Family Member. We both have iOS 18.1.1 and Sonoma 14.6.1 (and it used to work)
iPhone 15
Add both accounts to each device. So you would add drdavedmin@xxxx.com and wife@email.com to your iPhone and Mac. She would add the same accounts to her devices.
Add or remove accounts in Contacts on iPhone - Apple Support
Add contacts from iCloud, Google, and more to Contacts on Mac - Apple Support
