What's the reason that I can't login Cody Coursework?

I have applied and activated a MathWorks account. Yet when I went to the Cody Coursework Login page and clicked the Sign In button, the page was refreshed but remained at the same place. No change could be seen. What is the matter? Thanks a lot.

Same problem with you.

Are you still having issues with logging in? Could you try clearing the cache or login a different browser?

[Siyu Guo]

The problem is still there, dear Santosh. I tried chrome and edge, but nothing changed. Clearing cache didn't help, either.

I have encountered the same problem and clearing cookies solved it.
