New Firefly editor broke our product-photo workflow; please restore the previous editor or a way to upload an image into Crop and expand

We use Firefly's Expand (Crop and expand) to put product photos on exact square canvas sizes for a rental catalog. After the redesign this stopped working. The Upload button on the 'Edit an image' screen opens only the system file picker, which cannot be used by automation or assistive tools. 'Edit image' on an existing result gives 'Can't load item.' In the prompt bar, the X to remove the 'current canvas image' reference does nothing when clicked. I could not find any way to switch back to the previous interface. Please bring back the previous editor (or a toggle to it), or add a way to drop an image straight onto the Expand canvas. This is currently blocking our work. Thank you.
