I have just started Level 2 - Sprint 1. It appears that there are currently no "Continue" buttons. (I have gone back and checked the Introduction section and that has the same issue.)
If I go to the next section ("1.1.4 Delete from List Using Selection"), there is currently no material, just a blank screen with the heading and a statement "Review this micro-lesson to learn about deleting items from very large lists.". Is this a known issue?
