Have the issues with the co-op bank connectivity been resolved?

Hi rebeccafield09-g, thanks for joining the QuickBooks Community 🙂 - we're aware of an issue where some customers are receiving a 590 error when updating their Co-operative Bank account, is this the same error that you're experiencing? 

If you are getting a different error code/message we have included a helpful guide on resolving bank errors here

Any questions on this let us know we'd be happy to help further.
