The fix is now official and will be in 4.22, and will soon be visible on GitHub.

I have tried the mentioned fix and rebuilt the ue4 editor and tried it again. But all I get is this black results. Any ideas? Is this normal? I am guessing that this may be normal … but if it is , then visualizing volumetric lightmap is pretty useless? other than checking out the density… ?

You will usually see the bounced light only around the probes that are near the landscape surface. Also make sure your lights are static so the bake actually happens
