I don't use it.  I have my own.  If the official sheet isn't being supported, there's many others through roll20.  WFRP isn't 100% supported.  Cubicle 7 put their focus on Foundry.  I don't like Foundry.  Too low level.  Too many things you have to configure.  Quite frankly, not worth the effort.  Th char sheets are too small to read, and many other issues like that.  So unless you want to go to Foundry, mistake imo, find another char sheet.  Someone took my charsheet and posted to roll20.  He improved it to the point it's kinda hard to use.  There's a couple of others.  If you want you use mine, ping me in private.
