Is there a way to revert to "classic" invoice view? If so - please tell me how?

We're glad to have you here in the Community,mmvam. I'll provide insights about the new invoice view in QuickBooks Online(QBO).

Last May 6, QBO made updates to the estimate and invoice experience. It is to enhance its back-end technology for more features and faster development. The option to revert to the classic invoices is currently unavailable.

Please note that QBO is a web-based platform that is often updated. Its features, interfaces, and functionality change over time. You can see more of the latest news and upcoming product updates in our QuickBooks Blog.
