Hi there. Same happened on mine. VW told me there was a bulletin about this issue and it was put back in with some sealant to hold the corners in place. When visiting the showroom in Liverpool last week the Cali ocean display model had the same issue so doesn’t seem to be getting rectified even on a new vehicle.This is a common problem in very hot weather. You can push the beading back in yourself with a stepladder, a trim tool and some confidence.
Helps to have someone inside pulling the roof down a little if you’re in a beach/coast, otherwise lower it a little to create some slack in the canvas.
