It's not the action to take a screenshot, its the action to take a photo...with the camera.
I assume the developer of Android made changes in 8.0 causing the issue...lol? Though, I'm not claiming to know that as fact, so I wasn't really making any sort of claim as to who would be 'best' to fix it.
But, "Well just don't do that" isn't really productive advice. lol
I haven't really gotten around to testing other actions so far.
