iMessage not working for one iPhone user
I am unable to send a text using iMessage to my wife's iPhone 12 from my iPhone 12. It is forced to SMS. This is not true for anyone else's iPhone. I can send iMessage to all of them, including iPhone 12 users. I've tried deleting my wife's contact information and past texts. Nothing seems to work.
