Mavic 2 Pro. Vision Calibration Problem

[Cap Loz]

I'm getting in the Overall Status section on startup the "Recalibrate the Vision System" warning.
I'm connecting up the Assistant 2 OK but when I get to the calibration window there are no calibration dots or Red or Green boxes to continue with.
Any ideas anyone please.

Is this a new drone on initial calibration, or have you calibrated vision before? You have the drone powered up and connected to your computer with a USB cord?

I’ve had it for over a year now and never had to do the calibration until now.
Yes I have it powered up and connected to my PC with the usb C cable.
