You've come to the right place. There are few steps you can take to find the month's updated bank transactions, just follow the instructions below to get started:
Troubleshoot missing reconcile transactions
Start by navigating to the Accounting tab and select the Chart of Accounts section.
Next to the Bank account you'll be reconciling, click View Register.
Use the Filter (funnel icon) to sort the list so it only displays transactions in the month you're trying to reconcile.
From the transactions that appear, verify that there is no R in the checkmark (✔) column. This would mean the items are already reconciled.
Click Reconcile in the top-right corner of the page. Since you're likely still in the middle of this reconcile, click Resume reconciling.
Select Edit Info in the top-right and verify the Ending Date. If this was set to an earlier date by mistake, no current transactions may display.
Check out the attached video below for a quick demonstration of this:
With these steps, you'll have those transactions back in the reconcile function in no time. All of this information and more can be found in our Reconciling Hub here as well. Please know I'm always available here should you have any additional questions or concerns. Thanks for coming to the Community and take care.
