Hello and thank you reaching out to us in the Community, matthewshedd44.
I'll share some possible reasons on why bank accounts are not updating and the steps on how we can get the transactions.
QuickBooks automatically downloads the latest transactions every night. If the update seems to get stuck, an issue from the bank's end might be causing this, or you may need to complete some security requirements.
For the moment, let's do the manual update in QuickBooks. This helps update all of your connected bank and credit card account, and add your new transactions.
Here's how:
Go to Banking or Transactions on the left navigation menu.
Select the Banking tab.
Click the Update button.
After the steps, review the transactions. If your bank is still not loading the new data, please sign in to your bank's website and check any maintenance or security updates. In case you encounter any bank errors, you can check the solutions under Step 4 in this article: What to do if you get a bank error or can't download transactions in QuickBooks Online.
Utilize the trial version of MT Online to isolate the issue. It is designed to import into any bank or credit card in QuickBooks Online, so there is no specific setting needed. If the same error persists, there is an ongoing problem at your bank or connection.
