Why can't I do screen shots on my moto x after updating to lollipop?

[AC Question]

I have a first gen moto x, and updated to lollipop yesterday. Power and down volume does not seem to work to screenshot images. And I can't find any answers, anywhere.

Welcome to Android Central! It should still work the same way. Make sure you're pressing both down at exactly the same time, and hold for about half a second.
