I'm a little disappointed... I understand that you edited and uploaded it even though it's a basic lecture, but I'm perplexed. It feels like the lecture hasn't even properly started, but there are tabs in the lecture tab that aren't in my data panel. Is this something that the students who are paying to take the lecture have to infer and interpret on their own...? Even if you edit and upload an existing long lecture, you should make it so that people can follow the entire process, but it feels like it keeps cutting off and the flow isn't continuous. Even if you look at the posts in the community, the questions that were posted are all about the same thing, and compared to the questions that were posted in February, the Excel used in the lecture hasn't changed and it hasn't been re-edited... I ask for a quick reflection.
