Why is the bank balance on dashboard incorrect after reconciling?

Let me provide information on why this can happen, AJ45.

When the amount doesn't match, it could be there are outstanding checks, duplicate transactions, transactions that may have been modified or deleted.

To identify the cause of the mismatch, you'll want to do full reconciliation of the account.. For the detailed steps, you can check this article: Fix issues for accounts you've reconciled in the past in QuickBooks Online.
