Why can I see with some people that they've read my iMessage but not with others?
My read receipts is turned off, and so are few of my friends, yet we can still see when our messages have been read. I was wondering why this happens with some phones, but then not with others? Sometimes I can see when they've read it but not with everyone, even though all of our read receipts are turned off.
