Changed from iPhone X to iPhone XS. On the new phone I’m logged in to iCloud, iCloud Messages etc. But when I send a text to my GF (also using iPhone), the text is not added to our existing conversation. Instead, a new conversation is created where the top says “maybe MyName” (where MyName is my contact name). I update iPhone every year but have never come across this before. What the heck should I do to get “approved”?
