When we open the map it is like if we’d rise up a few hundred meters from the ground and we’d take a picture. In the picture, what’s on top is what we have in front of us, what’s on the bottom is what we have behind us. Once we have taken the photo, in any direction we rotate our device, the image remains fixed and we explore the map as it was when we opened it. What if instead of taking a picture we made a video? If that is, when we rotate the device in any direction, the map rotates accordingly and at the top there is always what is in front of the device at the time and at the bottom what is behind at the time.
For this to happen you activate the “Rotating map” option in the settings of the app, map section.
