Receiving message “you have been blocked from originating messages to ##########”
While successfully sending and receiving iMessages with a friend, all of a sudden I will receive the message “you have been blocked from originating messages to....” and my message will not be delivered, even as a text message.
Any ideas what is happening and if the problem is on my end or the other person? When I get the message, I have been receiving 3 of them simultaneously.
