New smart meter

Hi. I had my next smart meter installed 2 days ago. However, my display on the in home display does not show the traffic light system or my electric usage. I have read the booklet and tried everything, including turning it on and off but still nothing? Any help would be appreciated. Thanks.

Some info here:

Mine isn’t much use either. ‘Waiting for MPAN’, ‘Waiting for meter reading’, Waiting for Godot. All it does is show the time.
