Prerequisites have not yet been completed

Even after watching the video 4 times, it doesn’t mark the video as “seen”, and I can’t access the next resources. This is the web app’s response:

Prerequisite(s) have not yet been completed!

To move forward, please complete all prerequisites in Section 0: Welcome

Thanks in advance.

Edit:
Something to do with firefox’s extensions. Start in safe mode and you should be fine

Disable your ad blockers and non essential extension and log in with a log out once !
