Assignments locked

Hello ,I’m currently pursuing Course 4 of the Deep Learning Specialization, from yesterday all my programming assignments have been locked.

May I know what is the reason???

Did you reset your deadlines?

Yes I did, on the home page I see something named “auditing” with a locked symbol .

Did your assignment are still locked? I mean, after clicking on resetting my deadlines, they locked my assignments too.

I am now experiencing the same issue. Any clue to resolve this issue?
