Hello there, @-c2csiteservices.
Thanks for bringing this to my attention. I'm here to help share some information about why you're unable to connect NAB on your bank feed.
I'd like to inform you that we currently have a known issue about NAB bank feeds not downloading entries to QuickBooks Online. Our engineers are actively working with NAB to retrieve the file as of June 06, 2022, which contains transactions from June 17,2022.
I also recommend contacting our Customer Care Support team so that you can be added to the list of affected users. This way, you'll receive email updates of the investigation's status and be notified once it's been resolved. I've included the steps to contact support below.
In the meantime, you can manually enter your transactions or manually import them using a CSV file upload.
You can also check on this article on what to do if you get a bank error or can't download transactions in QuickBooks Online.
Feel free to message us back if you need further assistance with your bank transactions.
Our online banking team is actively working with NAB bank to resolve this issue as soon as possible. As of right now, we're unable to provide a turnaround time since this is on the bank's side.
On the other hand, I understand how it feels when a certain feature won't work. However, I can guarantee you that our Online Banking feature in QBO is working as it should. Else, all of our clients who use online banking will have the same complaint.
You can consider importing your transactions while waiting for the solution, like what AbegailS said above. Then, please contact our Support team, too, so they can link your account to the ticket for immediate updates.
Please don't hesitate to comment below if you have other concerns. I'll be here to help.
