My daughter was talking with a friend over iMessage. They were like playing a game where they search all emojis with a certain color. When she tried to send the message in this picture, the iPhone rejected, with the alert saying she was sending a nude. There’s nothing there, only emojis. What could’ve triggered the warning?
I don’t know, but start shaving off emojis to see when it’ll accept it and you might get some hints.
