> You can't unupload a photo under either the old or new system.

You can choose to upload many pictures. They will start uploading. Then, you change your mind. Some pictures were not uploaded yet. But they were scanned by the new algorithm.

I do wonder what happens in that case to the scan results for the photos that weren't yet uploaded. From earlier articles it sounded like the "voucher" is attached to the image upon upload, so it stands to reason that if you cancel an upload, results don't get uploaded for photos that didn't get uploaded. Who knows, though...
