update for anyone else: i found it by clicking into an interview, clicking the participant, and then got a popup notification on where i can find the ācontactsā database.
In bottom left of homepage
More--> Contacts (top of popup)
Hi, where did the āpeopleā database go? Iām looking in āsettingsā and used to see āpeopleā or ācontactsā under the Workspace subgroup but am not seeing it now
