When a GitHub account attempting to connect is already linked to a different connection, the connector currently enters a repeated authorization loop with no clear error message, leaving users unable to tell why the connection isn't completing. Suggested enhancement: Detect when a GitHub account is already linked to another active connection during the connect flow, and surface a clear message explaining the conflict and how to resolve it, instead of looping without explanation. Benefit: Users can immediately understand why a GitHub connection isn't completing and resolve it themselves.
