I'm here to address this bank connection concern and get you back to business.
Before that, did you encounter an error message when attempting to connect your bank in QuickBooks Online (QBO)? This way, I can make sure that we are on the same page so I can provide an accurate solution to resolve your problem.
For now, we can try logging into your QuickBooks account through a different supported browser. It will help us determine if the problem is related to the browser's settings.
However, if the issue persists, I'd suggest running the manual update to refresh the connection between your bank and QuickBooks.
Here's how:
From the left menu, select Banking.
On the Banking page, select Update.
If prompted, enter your Multi-Factor Authentication (MFA) credentials and select Continue update.
If you encounter any errors while updating your bank, please check out this article about fixing online banking errors in QuickBooks Online: Fix online banking errors in QuickBooks Online.
Also, you can manually import your bank transactions into QBSE using the CSV file. For the detailed steps, please visit this link: Manually import transactions.
Additionally, to guide you in categorizing your transactions in QBSE, please see this article: Categorize transactions. From here, you'll also learn how to create category rules and edit or recategorize transactions.
Stay in touch with me on how things go. I’m always here any time you need help. Looking forward to hearing from you soon.
