Team members are unable to see TFS repo

I followed what Ash suggested above and was able dig around and eventually resolve it for my case. Adding some steps here hopefully to help more people find the right page.

To change access from "Stakeholder" to "Basic":

1. Go to your project page > under "Project Settings", under "General" > "Overview" which is the default, you should see "Process" = "Basic". Click on the word "Basic", that should lead you to your Organization Settings.
2. Under "General" > "Users", you can see that yourself or some users have the access level of "Stakeholder" rather than "Basic". Next step is just to get someone who can, to change that.

In my case, team members role was stakeholder. It should be BASIC to see all repos.

If you are a "StakeHolder" in azure then, you have No access to Repos in Private Projects.

For my project, We had to purchase a Visual Studio Subscription before the repo setting became available.

Microsoft Devops - About access levels - Stakeholder access

Public versus private feature access: Stakeholder access grants access to features differently depending on whether you're working from a private or a public project. To learn more about public projects, see What is a public project.

Visual Studio subscription access: Visual Studio subscribers are entitled to Visual Studio subscription features as a subscriber benefit. When you add those users, be sure to assign them the Visual Studio subscription access level.

The system automatically recognizes their subscription and enables any other features that are included, based on their subscription level.

if you use azure devops server, you can change access from "Stakeholder" to "Basic",
