"More gestures" are not working because of downloading "Pearson OnVue" exam software
I have a MacBook Pro (13-inch, 2016), macOS Catalina 10.15.6 and lately I have and exam and I download "Pearson OnVue" software to do the exam. But when I removed it I faced a problem that all "more gestures" are not working, that shows Desktop or App Expose by using 3 fingers in the trackpad,
System Preferences >> Trackpad >> More gestures (this not working even if they are checked in check box)
What should I do to fix it ?
MacBook Pro 13″, macOS 10.15
