advanced data protection requires imessage - contact has imessage and is using it
I wanted to turn on advanced data protection and set up a few recovery contacts. I was able to request one be added, but I wanted my sister as one too and it wont let me add her, saying the user has to be using imessage. She has imessage. We use it to talk all the time. Why can't I do add her as a recovery contact?
