Issues with buttons in Sum Total Mobile App

Are there any users of Sum Total LMS who are using the Sum Total app (as found on iOS and Android)? On iOS, the responsive course I have created runs fine UNTIL it gets to the QUIT button. I have created a simple button that exits the course. The button "clicks" (makes a sound, and shows the animation of being pressed) but nothing happens. I have SCORM set to test (which I can pass with 100%, but I don't get completed status in the SumTotal app (it just stays "in progress"). If anyone out there is successfully using the Sum Total App, please let me know, I would love to know how you are doing it.
