Cubase Zoom/Scroll Using Apple Magic Mouse 2

I just got a Magic Mouse 2 for my mobile rig. Zooming in/out, left/right into Cubase using the MM2 is done in steps and not smooth. On the other hand, in Ableton, the zooming is very smooth–just like other Mac apps and the OS.

Is there a preference or setting I’m missing, or is this something to do with old Cubase code?
