QB retrieved no bank transaction from my linked account for 6 weeks. The bank sees no issue on its side. I can connect to the bank from QB. Mobile & desktop fail. Ideas?

Thank you for posting in the Community, @ghasking.

You can retrieve the transactions from your linked account in QuickBooks. I'll provide the steps below.

1. Go to Banking on the left panel.
2. On the Banking page, click on the Update button.
3. If you’re unable to connect, please wait for 2 or 3 hours and try again.

If you get the same result after updating the connection, you can bring transactions into QuickBooks Online by using the WebConnect feature. You can refer to the Import bank transactions from Excel CSV file to QuickBooks Online article for the detailed instructions.

If you receive an error message or code, refer to this article: Fix banking errors.

Also, you can check this article to learn how QBO process your bank and credit card accounts to download your recent transactions: Connect bank and credit card accounts to QuickBooks Online.

Get back to me if you have other questions. I'm always here to help. Take good care!
