I have the same problem, contacted support and they could not help. Recommended that I request to add the feature to disable/hide a locked bank account. I did so, 2 month ago and another one 3 weeks ago. Nothing happens and the closed bank account is still in a locked error state showing a wrong balance despite manual booking transfer from old to new business checking account. I did not even get a feedback. This is a serious issue for an accounting app and needs some prioritized attention. I do not even dare to show this to my CPA.
