It's said to be coming out of beta in June 2021 but if you're lucky they will come out in 2020. No one knows when yahoo is coming out of beta. The way yahoo is going it will be years more until they come out. They keep adding new features and such but they can't fix the one MASSIVE problem, ad targeting.
It is better YPN stays in "Beta" till they fix it. Otherwise, with the current quality of ad targeting, they will mostly get publishers who have been banned in Adsense.
