Per the GitHub API docs, I am requesting the repo scope which gives access to private repositories.
The user is presented with the following dialog, which also mentions private repos. They accept the application.
Despite this, when using the oauth access token obtained when asking for 'repo' access, I can only see public repos when I GET https://api.github.com/users/someusername/repos. No private repos are shown.
The user account is my own, and I have not revoked access.
How can I see private repos using the GitHub API V3?
