Hi david51,
Let's make sure to bring your transactions, so you can reconcile reconcile your bank account.
You can log in to your bank account outside QuickBooks, and download the transactions within the affected period. Then, you'll want to upload them to the Banking page. You can find the steps in this article: How to upload more than 90 days of bank transactions.
On the other hand, please know that you can still reconcile your bank account as long as you enter the transactions in QuickBooks.
Did the agent mention about investigating this? If not, please contact the Chat team again. If yes, please wait for the feedback from our Online Banking team.
If there's anything that we can help you here, feel free to go back to this thread.
