Error details

1-the notebook says that unit 3 is supposed to have a quiz but there is no such button.

2-the questions of unit 3 are not readable (it seems some sentences in latin, maybe this rings a bell to the developers).

3-one of the steps of unit 3 generates this error in the screenshot, it seems it has already been reported here:
Error: "no matching package named 'std_msgs' found"
