Can't Progress - Python Video

I have watched this video from beginning to end, twice. It’s not giving me credit for watching the video. Is anyone else having this problem?

edit: ok… 4 times now. no credit. no jumping to the end. no pausing. no credit.

Can you click on next at the bottom of the page? I think that should update the syllabus checklist.

Yes, I clicked next. I also disabled every addon (Firefox). Still the same thing. I changed over to Chrome and it finally worked. Someone didn’t program that page to work with Firefox… tsk tsk.
