Thanks for pointing this out, I am looking into it now. The matching is working well for “ known “ relatives so there may be something off with this file. I will let you know what we discover.
I also wanted to add, that if you add an email address to your profile then relatives can communicate. It can be any email and doesn’t have to be the one you signed up with. We made every section of the profile fields optional so you can control exactly how much or how little you share.
