A:AnswerYes, the camera hole is sized for the 4th Gen IPad, and is square. I will include a picture that will show the shape in the Zagg Rugged Book cover with my 4th Gen IPad Pro.
A:AnswerI had the same problem at first with mine. Page 3 in the instruction book covers pairing to your device. Make sure the iPads Bluetooth is on. Then you have to push and hold the Bluetooth 1 or Bluetooth 2 button for 3 seconds on the keyboard. The blue pairing light with start to flash on the keyboards power button. Now it should show up on the iPad and you can select it to pair with it.
