To complete your course, please ensure there is a check mark next to all video lessons and all completion indicators show 100%.
Then, the "Complete Course" button (as shown below) will appear. Once that button appears, your course is considered complete (whether the button is pressed or not).
If you are still having issues with moving your course to completed status, please close and re-launch the course and ensure that your progress is saved in addition to refreshing your Cornerstone transcript. The course should move to completed status once those tasks are done and you are welcome to exit the course.
If you are still experiencing issues, please reach out via the Help widget in the course player.
