At first Chrome back/forward gestures stopped working after upgrading to MacOS Big Sur. I went into trackpad settings, unselected and reselected "Swipe between pages". It still didn't work. Then I changed it from 3 fingers to 2 fingers.
You can say it "works" now, but it goes the opposite direction. To go "back" I swipe right. To go forward I swipe left.
"Scroll direction: Natural" is selected. If I unselect that it fixes this problem, but then the vertical scrolling direction is reversed.
Anyone else seeing this?
