I am reading that the following is the effect of using Audience Analytics.
"Customers used to integrate the two of them using DIL through Data tag Management, step that won’t be necessary to be done from now on. DIL should be removed and replaced with the Audience Manager module alongside the App Measurement code. "
With the change introduced in previous release, DIL code is no longer needed. However, you can keep that on page and the integration will work. The only consequence you might face is double server calls.
