Unintended Message Recipient
For the past couple weeks when I send my son an iMessage or text message, he receives it. My screen shows the message going out only to him. His phone screen shows the message from me, but it also shows the contact number of one of his friends as a recipient, as if I were sending a group message to both of them. The friends contact information is not stored as one of my contacts. The friend does not receive the message I sent, but when my son replies back to my message, I do not receive his reply, but the friend who did not receive my original message receives his reply back to me.
We’ve deleted each other as contacts and re-entered them. My son deleted the friend as a contact and my messages to my son still show the digits of the friends number as if I’m sending a group message.
Any ideas how to get this straightened out?
