By default, whenever you resume a course, the course player directs you to the last played component.
In order to make sure that you start the course from the first component, you can add the following parameters to the end of the course URL:
URL parameter: &forceStart=true
Example: https://demo.creativas.io/wiki/courses/playcourse.action?course=30736546&forceStart=true
URL Pattern : {BaseURL}/courses/playcourse.action?course={courseId}&forceStart=true
