How to enable 3-finger drag in Catalina?
In Accessibility, I can't find any option for 3-finger drag in Trackpad settings.
Accessibility > Pointer Control > Trackpad options > Check "Enable dragging" > Select 3 fingers drag from the drop down
Try to use spotlight(command+space)to search the Accessibility, and then you will see. You cannot get there from System preference >> Trackpad. Hope you find it helpful.
