RE: Who knows Whom settings not showing
I have the exact same issue.
I have installed premium sales insight settings as per the instruction to get "Who Knows Whom" feature available. After the installation, only Who Knows Whom is does not appear in the settings.
As what others have suggested, I suspect that maybe my environment is not on the North American Region, as Who Knows Whom is only available for that region, but as I checked in the admin power platform, the environment's region is in the US
I can't seem to find any MSDN documents on why this is happening. Is it because I'm using a Trial type environment?
