If you see a "Duplicate connection — You already have a Robinhood connection" message when trying to reconnect Robinhood, it's because the previous connection had a failed authorisation flow that got stuck in a pending state.
You can safely proceed by adding the connection again and selecting "Yes" when prompted with the duplicate connection message. This will not import duplicate holdings or transactions.
