Tell me one good logic how is that gonna be a win-win situation?
This totally gives a favor to the buyer and I don't see any single benefit for the sellers. The logic is that sometimes buyers need more time, OK, that's fine. Without the consent of the sellers, they do it instantly. Then why not give the seller the same feature that they can extend the delivery time without buyer consent instantly? Don't you think sellers aren't sometimes facing crisis moments?
OK, let's skip this part, sellers don't have any value to this platform for a long time!
It will allow buyers to extend the review time 5 days more which means now the total review period will be 8 days. Where is the seller's benefits here? Why doesn't Fiverr instantly release the fund after 8 days then? Fiverr again takes additional 7 days to release the funds. So the total duration for such a project will be 15 days. This is really disappointing.
