Expandable Notifications Defaults?

[mattbooty]

I got a DNA, and at first when I would get an email or a gmail message the notification would show up expanded. Then about a week ago that stopped. Now I know you can pinch out or swipe down to expand it, but it used to just open up expanded which was sooo much more convenient, especially for trying to do a quick check of new messages one handed...

How did this change? Is there a way for me to change it back?

Thanks!!!
