Family Sharing
Ever since my husband and I upgraded to iOS 18 his phone seems to think it is me. His iMessages all went away. And now if I send him a message it says “To you and then my name”. Also when he goes to fill in forms it shows my information. We have check and his Apple ID is and made sure his iMessage app shows his phone number and his Apple ID. iCloud shows his Apple ID as well.
