Here goes: TAs have graded the students work which they uploaded. However, the students cannot see this annotated PDF.
The instructors can see the annotated PDF in the student's assignement workspace.
I have attached screenshots from both sides. We had to request students to send us these screenshots as it seems you cannot set a student role to test this.
Our IT dept has gone belly up, please send me your ideas. Thanks.
Side note: it says the student can still edit after due date. I enable cutoff date after the sshot was taken. So it's probably locked on the student side now (wouldnt it be great if we could test frm the student PoV?!)
