Hello there, jperatt1957.

We appreciate you sharing the steps you've performed to resolve the issue. Let's go over some basic troubleshooting steps so you can use the Invoices function seamlessly. 

To begin, we'll have to log in to QBO via incognito mode or private browsing. Then open your customer's invoice from there.

Here are the shortcut keys to bring up a private window:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P
• Safari: Command + Option + P

If you're able to view the sales entry and the program automatically directs you to the customer record, clear the cache and cookies to improve the browser's overall performance. Otherwise, use another supported browser to see if the issue is with the current one.

If the issue persists, I suggest contacting our QBO Care Team for further investigation. They can also create a ticket if there are many users affected by the issue.
