Is anyone getting recent issues with there products and services list when editing or add a new product.

Let's resolve the error you're having so you can add or edit a new product item, @sarahrayside. 

There are times that the browser you're using has information stored that's stopping or causing the error when adding or editing an item.

I recommend using a private browser or an incognito window when trying to add it. Then, you may clear the cache in the one that you're currently using if it works. Here’s how:

• For Chrome, press Ctrl+Shift+N.
• For Firefox, press Ctrl+Shift+P.
• For Safari, hold down Command+Shift+N.

If it works, here's how to clear cache and cookies to fix issues when using QuickBooks Online. Once you're done clearing your browser's cache, restart your browser for the changes to take effect. If not, try using other browsers.
