There is no place to upload my assignment, anybody facing the same issue?
Hello @M_Matar ,
Welcome to the community!!
Click on launch notebook.This will redirect u to your notebook workspace.Then after completion of coding, click submit assignment.
You won’t have to upload anything.
With regards,

Hello @M_Matar!! Su here! 
The submissions are structured in a way that once you click launch notebook, another web page/tab will be opened up automatically, when you complete it, there should be a submit assignment button! (Personally find this really efficient!)
