Many people are very confused about this account, whether there is any problem?
No account problem no this is new update from your Fiverr. Fake buyer request on Fiverr has increased so much and spamming too. This is why there is no longer a buyer request option on Fiverr. But the good news is that if you publish the gig well and researched, then if it matches the buyer's requirement, your gig will be sent a brief or a notification will go to the buyer. And buyers can easily contact you through the brief.
But now you have to write the gig well and researched so that it matches the client's requirement. Those who are new in this field can take advice from the old seller that how are the buyer requirements then you can keep most of the requirements in your gig.
