I am creating a Model>Predictive Audience. My Model Inputs are two segments which are using a cross-device data source (set up with a CRM ID). Those two segments in turn are built using a trait, only one trait for each segment, that are onboarded and also uses the same cross-device data source. What data source should I use for the Predictive Audience?
To make sure it's clear here's the setup again.
Trait 1 is built with onboarded data. Data source is cross-device.
Segment 1 is built using Trait 1; in segment rules Trait 1 was added in and nothing else. Segment 1 uses the same cross-device data source as used in Trait 1.
Trait 2 and Segment 2 is also built the same way as Trait/Segment 1.
Predictive Audience uses Segment 1 and 2.
What is the proper data source to use for this PA? We have another cookie data source. Should the PA use the cookie or cross-device data source?
