Huawei P8 Lite Screenshots?

I have a Huawei P8 Lite (the old one) and whenever I want to do several screenshots in a row, that's not possible, but why?

I also have the latest emui version or what that means

Also, this key combination with the soft key and the power button does not work

Maybe you just do not hold the two buttons down long enough or you just do not push them at the same time. I have the same phone and it's normal that you can't take multiple screenshots in quick succession.
