I was about to submit to the auto-grader but couldn’t save my work! So I tried to reload the lab and I got the error to load the lab. The reading section says to click on Coursera logo in any other lab to navigate to File Directory. I am unable to do so and cannot access the directory other than the lab I have currently opened. Let me know if there is a solution to this or do I need to wait for some time for it to get fixed?
When you can’t save your notebook, typically it means the kernel is still busy running the code in one of the cells.
You can restart the kernel via the menu.
