Did they possibly add anything new to it?
I had some completed courses from over a year ago but when I click on some lessons they’re not completed bc of the new material.
I take back what I said (b/c I was on mobile when I replied earlier).
I looked at one of the course–Analyze Data With Python–I’d completed a couple years ago and it says it’s not completed. I drilled down into each part of the syllabus and each has a checkmark but says “resume” on it. Nothing is incomplete. I’ll submit a bug report on this.
Did you submit a bug report too?
Did you go through each lesson on those courses to verify that they were in fact completed? I checked two of my courses & one was complete while another had new material that I’d not done yet.
