During delivery Steve mentioned closing the rear hatch over top of latch. If your car is like mine there is a temptation to apply too much pressure and not be precisely over the latch . I managed to crack my rear glass panel in the process. Concierge, Milikken took care of things immediately but don’t be me . Hopefully these pictures help. The blue glass cleaner sheet is over the latch. Always push down easy at this point.
