Hello, I have the exact same problem. The next module says "You cannot view this item yet" even after doing all the quizzes in this module 100%. After "Scroll back up to see the next module and exit buttons" is displayed on the Cloud Intro Part 4 page (Module 2), I scroll back and I see no exit button, just the Next Module at the very top right. On clicking that, the next module doesn't load. Browser is Firefox, OS is Windows 10.
Extremely frustrating. Please explain what I must do to proceed with the course OR fix the course so the modules load. I've done several CP online courses (the flash ones such as eg. SBM) and this (CCVSA) is the first one to show this problem.
