 # License Plate Detection
 
-Draws a magenta bounding box around license plates located in an image.
+Originally, this workload returned an image with license plates annotated with magenta bounding boxes. It was modified to return a textual representation of the bounding boxed to reduce network payload. However, the resulting coordinates seem to not match the coordinates of the source dataset suggesting that the image may have been resized or something.
 
-The first request seems to succeed, but subsequent requests crash out due to a socket error.
+Solving the problem is deferred to a low priority task because we previously verified that the workload is running when it returned annotated images.
