Please note: currently the operating system for Chromebook machines are not fully supported by our video player. If you encounter video playback issues while using a Chromebook, and none of the troubleshooting steps above resolve the problem, please contact our support team. They will do their best to resolve the issue for you.
If you're using a Chromebook machine, we'd recommend enrolling in a free course, or previewing a course, to evaluate the video playback before making a purchase.
