I cant search by invoice number since the upgrade, only allows see a sample or create new. How do i search by invoice number now?

Glad to have you here in the Community, @lov2bhntn.

I'll be providing you with information about searching by invoice number in QuickBooks Online (QBO).

The ability to search the invoice number directly in the All Sales tab is currently unavailable in QBO. However, you can search the invoice number using the Transaction search function. To do so, here's how:

1. Log in to your QuickBooks Online account.
2. At the upper right corner, click on the magnifying glass icon.
3. Type in the invoice number.

Additionally, if you want to automatically locate the specific transaction, you can use a workaround by clicking on Go to transaction search and then entering the invoice number in the Reference number field.

Here is a photo for your reference:

Let me know in the comment section if you have other questions about your invoices in QuickBooks Online. I'd be glad to help. Have a good one!
