There are many different brands of these screen protectors and most of them are not designed specifically for the iPad Air 4. To fit more than one model they have a very large sized notch at the top of the screen to accommodate some older camera models. The latest Air 4 has a tiny new camera and only requires a tiny hole in the screen protector. It's also very easy to install and they give you 3 protectors in the box so if you screw up installing 1 or 2 you're still good.
