Publish the assignment
There are three situations in which you won't have access to your feedback:
If an assignment isn't published yet, you'll see the message "Assignment not yet published" in your Student Console.
If an assignment is published but your submission isn't graded yet, you'll see the message "Your submission hasn't been graded yet".
Finally, if an assignment is published but your submission hasn't been uploaded to codePost yet, you'll see the message "Your submission hasn't been uploaded".
