Delay in delivery with panoramic roof

Hello together. I ordered a Grandland B in January. I ordered the comfort package for it. Now there are different statements that there are problems with the panoramic roof. My FOH also told me to have heard about it, but my delivery date was still standing. I read from other people who ordered this, that the delivery time can be postponed by up to 12 weeks. As a reason I have of delivery difficulties of the panorama roof and that the roof mmel when opening and closing the doors should move. Maybe someone here has more or more detailed information about it. VG Tom
