If I try sending message to someone it will only let respond to their message but if I use their email after I type the message the send button is not highlighted and says incorrect email but it is the email the person the message from?
I can only respond to messages. I only can send messages to a persons iPhone but when I try to send to their iPad it says incorrect email for said person but it the email they used when messaging me?
iPad, iOS 5.1.1
