If you didn't receive any error messages, you can sign in to your bank’s website to check if everything is working on their end. Then, manually update your bank connection to get the latest available transactions. Let me guide you how:
Select Banking or Transactions from the sidebar menu.
Go to the Banking tab.
Choose the appropriate bank account.
Click Update.
You may also perform some basic troubleshooting steps to isolate the issue. At times, the accumulated cache in your browser causes sync and connection issues between your bank's website and QuickBooks.
To start with, open QuickBooks in a private or incognito window. Please refer to the shortcut keys below to open one:
For Google Chrome: Ctrl + Shift + N
For Mozilla Firefox: Ctrl + Shift + P
For Microsoft Edge: Ctrl + Shift + P
For Safari: Command + Shift + N
If it works, you can go back to your regular browser and then clear its cache to start over fresh.
In addition, I would also appreciate it if you can tell me the name of your financial institution so I can check on my end for any ongoing investigation.
