I have a question for anyone who may know how to this issue. I received an imessage this morning and it said it was from "unknown". When I looked in my contacts, I have the person saved and I have the right phone number and all saved. Does anyone know why they are not coming up as the name saved in my contacts and instead showing up as unknown? I have been messaging back and forth with my wife and all of her messages show up with her name. This is the first message that I have received from someone other than my wife. Any help would be greatly appreciated. Thanks
