## I can't see the changes to a linked third-party repositories or search for results of those changes
<a name="troubleshooting-detect-3p-changes"></a>

**Problem:** The changes in my third-party reposiory aren't showing up in CodeCatalyst.

**Possible fixes:** CodeCatalyst currently doesn't support detecting changes in the default branch for linked repositories. To change the default branch for a linked repository, you must first unlink it from CodeCatalyst, change the default branch, and then link it again. For more information, see [Linking GitHub repositories, Bitbucket repositories, GitLab project repositories, and Jira projects in CodeCatalyst](extensions-link.md).
