When you add a click to reveal and set the setting "Move to the next slide when the widget completes" to on, it never works in the course. I had to add a button to allow the user to continue on in the course. I would also add a "widget complete" variable so I can use logic to determine the status of a widget when I need to add conditions. For example, I only want my "Continue" button to appear when the widget completes, but there is no options to find the status of the widget.
