I've tried to optimize it a few times during the period. It worked for me before but nothing happens now. Surprisingly whenever I change the gig thumbnails to better ones suddenly my promoted gig option gets disabled, and that's funny tbh.
That's my main gig - https://www.fiverr.com/s/wvm0zA
As you can see in the screenshot in the main post there are 5 cancellations out of 200 orders among which CS handled 4 and told me these won't affect my metrics. But what I have learned so far from the forum is that it is affecting now even if they were handled by CS in the past.
The 4 stars that I'm usually getting now are because of the new rating system. Buyers are confused. Even if they are happy with the outcome they end up giving a lower rating and that's unfair, to be honest. Even if Fiverr wants us all to come out of the 5 star mindset on the platform it shouldn't be forcing buyers and confusing them in a way they end up giving such ratings. They could have taken ideas from their competitors and maybe should've added a few more options to rate stars and that would have been fine but I do not think this is the right way.
