How do I take screenshots in HyperOS?

I know this might seem like a dumb question, but I recently updated to HyperOS and can't figure out how to take screenshots. Up until now I've always held down the square button on the bottom of the screen, but now that option seems gone. It's either swipe down with three fingers, press power+volume buttons (which doesn't work for some reason) or use the control center screenshot button. Is this normal? Is there any way to fix this?
