Can someone help me. My navigation menu has disappeared with one of my clients and don't know how to get it back

I can help you, darryll2.

In QuickBooks Online, the navigation menu can sometimes disappear due to various reasons. Here are a few steps you can try to get it back:

First, try refreshing the page or use a private or incognito window. Sometimes, a simple refresh can bring back the navigation menu. If that doesn't work, you can clear your browser's cache. Sometimes, stored data can cause display issues.

Check if you are using a supported browser. QuickBooks Online works best with the latest versions of Google Chrome, Mozilla Firefox, Microsoft Edge, and Safari. If the issue persists, you'll want to access QuickBooks Online from a different browser or device to see if the problem is specific to your current setup.

Let me know if you need further assistance.
