I am not whether it’s the right place that I post this questions. I cannot watch the first video on day 3, and also I could not download the slides of day 3 properly. There are no problems for the videos and slides for day 1 and day 2.
Thanks for pointing this out. I really messed up something with that first video!
I’ve fixed the link for the slides so they go to the correct spot. I’ve re-uploaded a video that is more than just 12 minutes of a black screen. That will be ready as soon as Youtube is done processing it. Probably within 15 minutes of this message being posted.
