If I’m not mistaken, the maps got a grey overlay when scrolling also showing the message that you could zoom in the map holding ctrl (I think) while scrolling. This option seems to have disappeared? on the homepage I can’t zoom anymore (only with the buttons or double clicking). On detail pages I zoom automatically when scrolling.
