Any thoughts on troubleshooting this, guys? having an issue with multi-touch gestures sometimes not working intermittently. three finger/four finger actions work, but zoom + two finger swipe to show notification center are not working. i am also using better touch tool, but only with settings on the touch bar. turning BTT off doesn't fix it. the only way it is fixed is if i go to settings, manually turn on and off zoom / two finger side swipe and then they start working again. thoughts??
