Attribute and audience groups are created within the data layer. Starting with version 8.0.0, every data layer automatically includes an attribute app and an audience app. These apps are created in the background whenever an attribute or audience group is defined.
Within a data layer, several pages are accessible via the left navigation bar. The apps that are created in background on top of the data layer can be seen in the Dependencies menu via the dependencies icon ().
Clicking on an app name will navigate you to the specific app, which can also be done directly from the Audience -> Apps menu.
Note: Before version 8.0.0, users could create multiple attribute and audience builder apps within the same data layer. As a result, customers who used the Audience module prior to 8.0.0 may have multiple attributes and audience apps under a single data layer. However, customers using the Audience module from version 8.0.0 onward will typically have only one attribute app and one audience app per data layer.
