Fiverr Brief System Explanation

[graphicshah]

I have been working on Fiverr since 2020 and earned almost above 10K but as Fiverr ended buyers requests and introduced the brief system, my gig went down and I getting no orders everything is finished, from getting 5 orders in a day now I get 1 order in 2 3 months, my gig title, thumbnail, description everything is optimized but still i don't know what a reason behind all this
