There is a critical error in the grading system in this lecture.

I cannot be proceeded because it is marked as an unconditional wrong answer.

I've had a lot of chat support, but I've only been told I'll find a bug and fix it.

I'm paying for the lecture, and I'm very disappointed that I can't get the correct service. I'll give up this lecture.

I want to learn. Locking me out of the course labs after the course is over is stupid. Grade or don't grade the lab, I don't care, but let me review the lab to learn. Additionally, preventing me from providing feedback to coursera directly leaves me with the option of providing the information here.

I can't log in the Qwiklabs. I reached support. They don't idea how to help me. The credentials generated by the lab don't work. I can't continue wasting my money, wasting my time, and learning nothing. It is a shame.

The course isn't put together well, it has not been tested and you frequently have to re-do the labs as they are not recognised in the main part of the course.

The progress of the course has been rolled back since some moment
