When QuickBooks is acting strangely, it can be due to issues with your browser. Let's perform some basic troubleshooting to resolve the problem. Log in to your QuickBooks account using a private browsing window.  

Here are the keyboard shortcuts for different browsers:

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

If the above process works, return to your default browser and clear the cache. Otherwise, consider using another supported browser.

If the issue persists, I suggest contacting our support team again so they can pull up your account and further investigate the root cause of this.
