Three finger swipe in High Sierra
I've recently updated my 2015 MacBook Pro to High Sierra, but the three-finger swipe between full-screen applications appears to have stopped working. The three-finger swipe now appears to be similar to the two-finger swipe, although I'm sure my fingers haven't shrunk.
I've tried going through Systems Preferences/TrackPad/More Gestures to check and they're all active. I've even unchecked and checked the lot to see if that would help, but to no avail.
Has anyone else seen this issue?
MacBook Pro (Retina, 15-inch, Mid 2015), macOS High Sierra (10.13.1)
