We thought we were behind by miles just changing over to .webp images on our website this Fall, and I was shocked when I saw they weren't being supported in ShipStation. Products with .webp images are just blank in the pick list.
We can't pack orders easily without the images and are now seeing a jump in the time it takes for a single orde. Not supporting these common image types leaves too much room for mistakes and is costing us in time.
