Have Marshmallow, No Vertical Scrolling for Apps list

[TheRevMikeS]

LG v10 running Android 6.0

Wanting to scroll apps vertically per Marshmallow feature.
Scrolling was horizontal on Lollipop.
Now running Marshmallow.
Still horizontal scrolling.
Tried Google Now Launcher. Still no vertical scrolling for apps list.

Any hints?

Thanks!
