It's not your account. It's delayed for some reason.
I have checked several times since morning but same here. I hope that it will be updated soon.
No Upwork official announcement Or response about it here. They should update us because mostly freelancers wait and curious knowing about it.
Job Success Score is supposed to update today for many of you. Please, allow until the end of the day for it to update. The team will investigate if it doesn't.
Thank you for your patience.
JSS did finally update yesterday. If you select: "Find Work" and then "My Stats," you'll see the date of the update (4/30).
Of course as Vladimir stated JSS's certainly can remain the same; sometimes for long periods of time.
