Hi, I'm wondering if anyone else has this problem that the Smart Keyboard for the 10.5 iPad Pro is not laying flat on the desk. Once I unfold it there is always a big space between the desk and keyboard. Only afterawhile the space reduces between keyboard and desk and is almost perfect. When I then fold it again and unfold it afterawhile it is back to the bigger space again. Is this something that is normal and does it get better with time?
