I normally have my students send me their share link for one of the challenges in the last step of each lesson. There is no Share button for the challenges in Lesson 9. Is there a reason for this?
I would recommend you reach out to firstname.lastname@example.org with a request for that specific level. I think sometimes there is a reason, but it may also be the case that they can add one.
I’ve already passed the lesson, so I won’t be following up on this.
