I enrolled in a course and started to watch videos and even successfully made the quiz. In the sidebar I always had green marks showing my progress. Now, I get the information to enroll in the course and to start learning. Also the time line for handing in peer reviewed material has changed.
Maybe the reason is that I could not watch the videos fully as the streaming always stopped after 1 minute or so. Thus, I had to download the videos for watching.
Thank you for any help here.
