Screenshot attempt turns off device?
I have no problem taking a screen shot on my iPhone. I'm trying to do so on my wife's iPad mini iOS11. However, I've tried 3 times and 3 times I've turned off the thing. I'm pressing, at the same time, the power button (at the top edge, right end of the device) and the home button (bottom, center of white frame).
This isn't a difficult task yet I fail to see what I'm doing wrong?
