My wife uses iOS 14 on her iPhone 7 plus, as I do on my iPhone 11. On both telephones, if one goes to"Show my caller ID," there is no toggle-switch shown, but instead a small daisy-wheel spinning around and around. Despite that, my telephone does show my caller ID, while hers does not show her caller ID. Instead, what it shows is merely her email-address. How can this be put right ?
