I am new to code.org. I made an account back in the spring, but I didn’t use it. On Monday I added my students to Principles of Comp Sci AP 18-19 on code.org. They are all added, but they can only see 17-18 materials. They have the same drop down menu that I have that allows them to toggle between years. If they choose 18-19, nothing shows up, even though I have set Unit 1 to visible and I have unlocked the pre-course survey. If they select 17-18, they can see the survey (they went ahead and took that survey today) and they can see anything else that I have unlocked.
What do I need to do to get them to be able to view the 18-19 materials?
