This might have something to do with your browser, eggslnt.

To confirm, try logging in on a private window. Here’s how:

• For Chrome, press Ctrl + Shift + N.
• For Internet Explorer or Firefox, press Ctrl + Shift + P. 
• For Safari, hold down Command + Shift + N.

Being not able to see the alert privately indicates the said issue. Switching to a different browser would also help to fix this. Below are the ones supported by QuickBooks Online:

• Google Chrome
• Mozilla Firefox
• Safari 11 or newer
• Microsoft Edge 

If this won’t work, I’d recommend contacting our support team. They’ll be able to help you investigate this further. 

Here’s how you can reach out to them:

1. In QuickBooks, click Help at the top. 
2. Select Contact us. 
3. Enter your concern about the Banking Alert. 
4. Click Let’s talk. 
5. Hit Get a callback.    

Always consider posting your questions here if you have other concerns.
