I am changing the logo and formatting of On-Prem DV.  I was able to find the css of the logo through the inspect function however, I cannot find the folder/file location on the server.  Has anyone tried to change the "skin" of DV? I am guessing it is similar to the analytics.ear file with Classic OBI.
