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.

They failed MISERABLY!!  

Feedback has been left. By me, as well as HUNDREDS of others, dating back to at LEAST April, before they rolled this out for all.  Does no good. No one cares. Especially the boneheads that created this mess.
