What's Wrong?

When working with Claude Code on the Web, you're prompted to install the Claude GitHub App, and you have the choice of where to install and configure it to.

After installing it to an organization, as part of a larger enterprise, which organization uses GitHub's IP Whitelist feature, and enabling the setting to allow GitHub apps to manage it, so that Claude can have access to it, no repository still is fetched from any of the selected, or when giving access to the entire organization.

What Should Happen?

I should be able to see my repositories.
