Why is the “Session Manual Ad Content” dimension no longer accessible in the Traffic Acquisition report?

Short answer

Recently the dimension “Session Manual Ad Content” is no longer available in the Google Analytics 4 traffic acquisition report. The reason is explained in the official documentation where Google recommends using cross-channel dimensions such as Source, Session Source and User First Source to understand multichannel acquisition data. Indeed the dimension “Session Manual Ad Content” is not recognized as a cross-channel dimension, and for this reason it is not selectable in this report.

The solution lies in the creation of a customized report or through an exploration report.
