Voice Control box keeps unchecking itself and won't enable
I just upgraded to Catalina. In System Prefs. I went to Accessibility and "enable" Voice Control ck box. It asked for Admin password which I entered and the box is checked. The admin password is correct and it accepts it. Within a few seconds the Enable Voice Box unchecked itself and it doesn't work. I've tried multiple times. The mic works and has been set to both automatic as well as Internal. The box just uncheck. I have waited to see if it needed the download but never saw that but may have missed it. Either way several attempts and no go. OS is all up-to-date. Thoughts?
