You could never actually purchase any AP on the DVC member site. Pre-pandemic, a member could purchase any new, discounted AP, including the DVC Members' Gold, under Parks and Tickets when on the member's MyDisneyExperience account, but you had to call DVC to renew the pass. As a result of the Pandemic, Disney stopped selling any annual passes to anyone online, but those who had an impacted annual pass in 2020 have been able to renew or buy a new one, including a DVC Gold AP, via calling the Annual Passholder phone number (or via calling Member Services).
