Same issue here, Im getting al good reviews from my old client, but still success score is 4. It's not even moving. Also, if anyone have noticed, mostly Asian sellers are affected, not USA based sellers, I always knew fiverr give more priority to US, the reason everyone knows very well why. But they will do this kind of things didn't expected. Upwork is more better than this, at least they have a proper criteria of ranking, not like fiverr.
