I have 63 reviews on my gig, just checked now and saw 59 reviews. is there anybody who has experienced this before and why?
I’ve heard of something similar (review numbers don’t match) twice that I can recall. One ended up being a visual bug and was fixed/updated by clearing cache/cookies, the other was a case of a review violating the ToS and thus being removed.
Whatever the case for yours is, you’ll have to contact Fiverr Customer Support for an answer.
