I have completed Every Quiz, Lab, Assignment, Videos.
I checked everything… it is also showing in the accomplishments in completed courses.
I have not received any certificate of completion. Please look in to it…
Right, we have no visibility into how any of that works or any control over it. But it’s also worth noting that in my experience, there seems to be a fair amount of delay in the system of issuing the certificates. I’ve seen it take single digit days up to a week. I don’t know if there is a human in the loop there or why it would be that slow. But exactly as Tom says, your only hope here would be to contact Coursera.
