The Co-operative Bank, UK has open banking but QBO now says it does not. It worked fine, but then stopped. Can't find an option to reload bank login details or reset.

Hello rtope 👋, Welcome to the Community, Hope you are safe and well, 

Some Banks may not be supported on Open Banking or the connection could not be established in time for the regulatory deadline, Our teams have been working round the clock to ensure we could continue to enable bank connections. Unfortunately, owing to the impending regulatory deadline and our legal obligation, we’ve had to take the difficult decision to disable connections. As a workaround you can upload your Transactions via CSV file until a connection has been found, Appreciate the fact its easier when theirs a live feed, but as advised we are working on this 🛠️
