When I do two figures from right to left, it moves forward in time. When I do two fingers from left to right, it moves backward in time.
Seems backwards. Note that when I switch to “Natural” for swiping in Settings, it fixes it. Not sure if there’s much to be done here, but maybe a pop up the first time someone swipes indicating that there’s a setting that can change this (or an option to make your GoRewind settings contradict your system settings).
