Grader doesn't work in C1W3_Assignment

[mario_amato]

I submit my notebook C1W3_Assignment ( Week 3 Assignment: Implement a Quadratic Layer) and I see in the tab submitted appear the submission waiting to be evaluated.
But after a few seconds the submission disappears and it is as if I had never submitted the notebook!
I would like to clarify that: I have obtained an accuracy greater than 97% and I have re-entered the comments in the last cell of the notebook and performed the “save & Checkpoint” before using the button to submit. All as described in the instructions.
