Hi all,
Apologies if this isn’t the best place to post this, but I actually came across this question because my students and I have also been running into this issue in the CSD curriculum - I only belatedly noticed the CSP tag here. I’ve emailed the support team and they’re looking into it, but two of the (many, but I can only put two links in) projects where this has been an issue are:
CSD Unit 3 Lesson 15 Page 9: shared page
CSD Unit 3 Lesson 17 Page 13: shared page
All students are using MacBooks and accessing the site on the latest version of Chrome. The issue is sporadic and I have not been able to predict when it will occur. There is no apparent link to internet connectivity. Refreshing the page occasionally solves the issue, and when the student moves to the next level, the issue usually will not persist.
