Confusing my AppleID photo and my wife's.
When I go to System Preferences/Apple ID on my Catalina iMac, I see my name, but often I see my wife's photo. I change the photo, but it doesn't stick. Sometimes when I go to Family Sharing and see my photo with here name (she is the organizer). This confusion happens on both machines and our iPhones and iPads, and has been happening occasionally for years.
Any idea what's happening?
iMac 27" 5K, macOS 10.15
