My map says Disconnected

Your map shows Disconnected · See why at the top, and its card on your panel says Disconnected. It means GitHub no longer lets SeeRepo read the repo: the SeeRepo GitHub App was removed from it, uninstalled, or suspended on the account or organization.

• Its map stays as it was. Nothing is deleted. The pill at the bottom says Map from its last commit instead of Up to date, and pushes aren't read.
• Whoever you shared it with still sees it, as it was, with the same word.

Bring it back

Tap Disconnected · See why, then Reconnect. It opens the SeeRepo GitHub App on GitHub: give it access to the repo again. When GitHub tells SeeRepo, the repo can be read again. On your panel, its card says Reconnect it to GitHub, which does the same.

Or take it off your panel

If you don't need it any more, open its settings: General, the last card, Take it off your panel. It leaves your panel and comes back to Connect a repo once you give SeeRepo access on GitHub again. See Connect a repo.
