Are there real people behind these responses to questions?

You realize that people have been happily creating invoices and using features common to nearly every invoicing program (e.g. Tracking Number, Ship Via, etc).  You decide to redesign the invoicing experience (great - i don't care)..   But I do care that when you redesign the experience you have taken away functionality.  In addition - you FORCE users to migrate to the new experience when it is not even half-baked.

You don't even provide a viable workaround to achieve the same result.

How about you allow people to continue to use the original invoice experience while you add the features that are missing.  I will move to the new experience when it is on-par with existing functionality.  For me - that will be when specific features are implemented in it.

Do you seriously expect us to submit feedback to gain back known lost functionality?
