Had error 1000 so followed instructions and disconnected. When I came to reconnect it won't let me select the account I need to link it to as says its already linked?

Hello margot3, Welcome to the Community 👋Can you ensure that the account has fully disconnected, please ensure it has been disconnected from the banking page and the Chart of accounts, Could you clarify that it has fully disconnected. Let me know how you get on. Thanks
