My Caller ID is not showing after updating my iPhone to latest iOS

Try and force restart your iPhone to see if the issues perist

1. Press and quickly release the volume up button.
2. Press and quickly release the volume down button.
3. Press and hold the side button.
4. When the Apple logo appears, release the side button.

If the Forced Restart WheelieNick suggested doesn't help, contact your carrier. Caller ID is their service.

Same problem here - and the toggle is missing in the phone app. Oh, and the “me too” button doesn’t work on this website.

Why do you need to use the me too button, the question has already been answered?
