Why don't I pass the assignment 1: Calculate Client Security Hash (Level 3 - Advanced Training)

I used the same email at acme-test and academy. I checked the result in acme-test and I passed. I don’t understand the reason why my score is 0.

I believe there is a fault in their systems, a lot of people are struggling to submit today, the UiPath guys said they will check what might be the problem, maybe let’s just layback a bit and try again later on
