Navigate to the Repositories settings page. Here you can find all the Repositories available in Velocity. All users that have admin privileges to add repositories will be able to add any of the organization’s un-added repositories, regardless of whose VCS account was used to provide access initially.

You can search for individual repositories in the top section and select errored repositories.

Re-sync, remove, unassign, and add Applications for multiple repositories at once using the "bulk actions" dropdown menu.
