Problem is resolved.  I had tried to transfer the figure with an animation applied to it.  Developers responded to me with a checklist and the one item I had not done was to set the figure in zero pose before transferring via the bridge.  So I do not have to fix anything inside Blender.  Here are my attempts at sending over a fresh figure without animation and in zero pose. Character is still applied inside Blender. No hand distortions.
