I would love it if Fiverr would consider instant payments for trusted and long-term sellers kind of like how eBay does it. For instance, if a seller makes a certain amount of sales or been an active seller for a certain period of time, instant payments should be a perk. I understand why it takes 14 days, but I think if a buyer is satisfied with their order and marks the order complete by leaving a positive feedback, then funds should be immediately released. If a person gets a negative review, then the payments may have to wait up to 21 days.
I would like for Fiverr to bring back the ability to see when someone has seen/read your message.
