I have a Surface Pro 3 type cover and a Surface Pro 4 type cover, and there is a delay with the tablet mode every time I snap the Sp4 Type Cover. It takes at least 7 seconds for the tablet mode to desktop mode to switch when snapping the SP4 type cover. When I snap the Sp3 type cover to my SP4, the tablet mode switches to desktop mode in a second. I even tried the Surface Book at the Microsoft store if there is any delay, and there was no 7 second delay. Is anyone having this problem or is my type cover a defect? Everything else is fine with the SP4 type cover but the switching part. Any help would be appreciated, thanks!
