Please for the love of your customers do the right thing and let us go back to V2. This is ridiculous.
I went to make a return and was surprised to see that in doing so the fields weren't autopopulating with the original shipment that went out to the customer. So I had to click back between the return screen and the original order (which of course meant my return was lost and i had to restart it) and memorize the weight and dimensions to pop them into the return. This used to autopopulate with the outgoing shipment's details. Why on earth would you REMOVE functionality?
