The same thing happened to me!
I changed over to HA payments after the Yapstone debacle at the end of August. I was approved for the so called advanced payments. I even went to the trouble of making a dummy booking for myself to get a concrete answer on the payment timeline. (I booked a one night stay, paid for it, and was then paid by VRBO for it.)
Since then, I have had ZERO inquiries and almost no page views. Absolute crickets, even for the competitive holiday season.
I did a test this weekend to see how my property is showing up. The answer: dead last, even if I search by price. VRBO was showing me listings that cost four times as much as mine for the same dates before showing my listing.
I tried live chat and also called customer service. Three representatives told me that I need to improve my listing and adjust my expectations blah blah blah clearly not listening or paying attention to the scenario. Finally I got on the phone with premier partner customer service and the man I spoke with told me the reason I wasn't showing up in searches is because I have no payment information on the account. All the bank info, gone, history of payments, gone, IRS form, gone. He said they've been getting a number of calls about this. I went through the entire process again and he said it could take up to 24 hours for the search position to readjust. I will recheck in 24 hours. Goodness knows how long my listing has been rock bottom and unseen.
Check your payment info in your dashboard and run a test to look for your property as well!
