your documentation explains how to get into the dialog, but it stops there. And it's the process of selecting a legacy contact from that dialog that is broken. I'm running iPhone v15.3.1. I was able to add a restaurant as a contact for example (then deleted it), but not my wife. I select her from my contacts list, it shows my wife's contact info, but nothing happens, there is only a button to go back to Contacts. Why? It doesn't say. I tried this 3-4 times and same thing happens every time. I guess I'll just leave her my account info and then she can do whatever she wants with it after I'm gone. Maybe this legacy contact isn't the best way to do what I want to do, which is leave her the photos videos music etc.
