I (hobby plan owner) was able to deploy from a private organisation repository to vercel until last Wednesday. However, suddenly we got this error:

1
Unable to deploy a commit from a private repository on your GitHub organization to the WONQ's projects team on Vercel, which is currently on the Hobby plan. In order to deploy, you can:

• 1
  Make your repository public or

• 1
  Upgrade to Pro. A Pro subscription is required to deploy from a private organization repository.

  • 1
    Click here to upgrade.

In the official document, it says if you are the owner of the hobby plan, you still can deploy and I think that’s what’ve been doing:
