I finished watching a video, but I can’t move forward; there is no right arrow to advance to the slide.

Videos must be watched in their entirety, without advancing the video player slide.  You can move forward and backward in the video, but the system must register that the full allotment of time was spent on the page. This was designed to have learners view the entire video in one sitting.   In the upper right hand corner of your slide, there is a video countdown timer.  It will inform you as to how much time is left on the page before you can advance to the next slide.  Always watch the video from start to finish or let the video run its full course, permitting the right arrow to appear.
