If Rating down below 90 No apply or Buyer Requests jobs. This is Biggest problem Freelancer. if freelancer no apply Buyer Requests. NO found job and time spend day to day, Freelancer hope every time, Given Oder Client but no Oder, Just Hope.
Client sometime Rating no like and Freelancer Submit better work but client given rating 4 or 4.50 or any wish so it her matters.
So my suggestion rating matter consider, Fiverr management.
