I added a profile for my friend Marci, who asked me to work on her family, and included her email address. As expected, it started out Unlisted. When she accepted the invitation, her privacy automatically changed to Private with Public Family Tree, she became manager and I was still on the trusted list, although no longer a manager - all this, too, was as expected. So far, I have added her father, grandfather, and great-grandfather, all of whom are Open.
When I added her as her father's child, her profile automatically became Unlisted again and now, since I am no longer manager of her profile, I can't change the privacy back to public family tree. I can have her log in and change her privacy, but ...
Why did this happen? Isn't there a rule that members cannot be Unlisted? If so, it seems like a bad thing to automatically change a member from Private to Unlisted when the first connection from the member to a relative happens.
PS Please note that her name still shows as manager of her father, grandfather, and great-grandfather, even though her profile is Unlisted!
