When creating or updating invoices, the product/service box is not showing anything but "Add New" when I click the box to add an item. Is there a way to resolve this?

Hi there, vips. 

We've received similar reports about the products/services dropdown not showing on invoices. I recommend contacting our Customer Support Team so they can add you to the list of affected users and get notified of updates. Here's how you can reach them:

1. Log in to your QuickBooks Online (QBO) account.
2. Click the Help button at the top right corner.
3. Go to the Search tab, then select Contact Us.
4. Enter a brief discussion of your concern and hit Continue.

Our customer support schedule for Plus, Essentials, and Simple Start users is from Monday to Friday, 6 AM to 6 PM PT, and Saturdays from 6 AM to 3 PM PT. If you are using the Advanced version, assistance is accessible 24/7.

Furthermore, I'll add this article to help you personalize the appearance and layout of your sales forms: Customize invoices, estimates, and sales receipts in QuickBooks Online.
