Hi,Need some clarifications here...Person: The ID used to define a single person. This ID can be mapped to multiple Audience Manager IDs.Household: The ID used to define a group of people. This ID can be mapped to multiple Audience Manager IDs.Question 1: Do they behave like tagging purposes or will it actually impact some sort of algorithm within the data source upon selection?Question 2: In which scenarios do we use Person or Household? Can anyone enlighten me on this?Thanks!
