I have updated the program because my email was not working, now my bank reconcilliation is showing as unreconcilled on 5 of my bank accounts going back to 2014. Is there any way that this can be updated easily?
when did you last update Manager? there had been few changes to Bank reconciliation in the last year.
maybe the below topics would help you understand and solve the issue.
Bank reconciliation statements can always be recreated if necessary, too. They are just reports. Make sure you have read and understand https://www.manager.io/guides/9235.
