New phone setup for secondary user?

I am the primary 1PW account holder and just got my wife a new Android phone. Downloaded and setup the app, logged in fine. However, the "Private" Vault shows my stuff when she needs her own Vault to show up as it used to. Can I simply "reset" this? Or do I need to send another invite?
