Hi, Please advise me on how to submit the assignment for Course 3, Week 1. The .ipynb file is not loading, and I have tried many times without success. This is becoming very frustrating. Could you please help me resolve this issue? ![Screenshot From 2026-08-01 18-26-37](https://global.discourse-cdn.com/dlai/original/3X/4/0/405fdea86214a17e614bb31dec2cb71d310957f4.png) Thanks ---

@Nada_Saif do you have the option to test from another computer? or from another browser in an incognito tab? The issue seems to be isolated to you. ---
