App Store Connect access not activated after enrollment (INVALIDITCUSER)

Hello,

I enrolled in the Apple Developer Program as an Individual a day ago. developer.apple.com shows the membership as active and the Program License Agreement is accepted.

However, App Store Connect says "Your Apple Account is not activated for App Store Connect" (error key INVALIDITCUSER) on every page, including /apps and /access/users. I have already tried signing out and back in, and an incognito window.

Has anyone seen this with a brand new Individual enrollment, and how long did it take to be activated? Is there anything I can do besides waiting?

Thanks!
