Welcome to the thread, Jamile.

I'm here to ensure you can see the category on the Product Categories page.

If the category you're looking for can't be found on the Product Categories page, I recommend clicking the Gear icon at the top of the ACTION column and setting the rows. Some of your categories might be hidden.

If not, I recommend performing some troubleshooting steps to investigate the cause of the issue. You can log in to your QuickBooks Online (QBO) account via incognito mode or a private window. This way, it confirms if the cache is the cause.

Here's how:

• Press Ctrl + Shift + N (Google Chrome).
• Ctrl + Shift + P (Firefox).
• Control + Option + P (Safari).

If you're able to see the category you're looking for, go to your default browser and clear the cache. See Clear cache and cookies to fix issues when using QuickBooks Online for more information. 

Otherwise, switch to a different browser like Firefox, Google Chrome, or Safari. The one you are currently on may be having a temporary issue with QuickBooks, and using a new browser for the moment will allow you to get back to work.
