Let's perform some troubleshooting steps to get the Navigation back on the left side of the screen in QuickBooks Self-Employed (QBSE), happinesshillcs.
If the navigation menu on the left side of the screen is missing in QuickBooks Self-Employed (QBSE), let's make sure that your browser window is maximized. Sometimes, if the window is not fully maximized, parts of the user interface may not be visible.

If the same things happen, we can perform some troubleshooting steps to see if the issue is within your browser. We can open a private or incognito window in the browser to open QBO with a clean slate and load fresh data. Here's how:
- Google Chrome: press Ctrl + Shift + N
- Mozilla Firefox: press Ctrl + Shift + P
- Microsoft Edge: press Ctrl + Shift + N
- Safari: press Command + Shift + N
If it works, go back to your regular browser and clear the cache to delete those temporarily stored files and browsing history. The collection of data over time can create corruption, however, removing this should fix the issue. Also, you can utilize another supported browser or device if this doesn't work. This happens when the current browser you're using has a temporary issue with the program.
