[significant drop on orders]

I have noticed the same. No new orders for the past month or so.
I feel like Fiverr really rushed the update.

[Fiverr Order Autocompletion]

Hello everyone,

I delivered work for a client 5 days ago. The order is still pending. The client has not accepted, and the order didn't autocomplete after 3 days, as is the case. Has Fiverr changed the 3 days autocompletion rule?

[Buyer's request]

The buyer request feature is no more.  Fiverr now matches you with buyer briefs. Now your best bet is to optimize your gig so that Fiverr algorithms can match you with the best buyers.
