I'm also having this issue and it's enough to make me stop using QBO.

When I create an invoice it forces me into using the new invoicing experience.  OK fine.

But where are my SHIP DATE, TRACKING NUMBER fields?  I had to add a custom field for Tracking Number but I can't use the drop down SHIP DATE calendar to select 12/18/2023 as ship date.

When I ship something, I automatically need to create a recurring invoice in 1 year from the ship date to pay for the subscription they ordered.  If I click on recurring invoice under the AUTOMATION tab, it doesn't copy anything over so I need to create a new invoice from scratch.  But the recurring template is the OLD invoice template that I need back.

Customer service doesn't seem to understand this.  They also seem to love rolling out "new features" without ensuring that the new experience is a good one.  They need to fix this or I am out.
