Magic Mouse no gestures with Yosemite

I just dusted off my Magic Mouse which I haven't used in a while and paired it with my Macbook Pro running Yosemite. It works fine except for scrolling. I checked under Accessibility and the scrolling is enabled.

Anyone run into this? The trackpad scrolls just fine but none of the gestures seem to work at all on the Magic Mouse.
