Which metrics section shows the changes made to your campaign, which optimizations were made, and by whom?

The Activity history section provides a detailed log of all changes made to your campaign, including modifications to settings, optimizations applied, and the user who performed each action. This is crucial for auditing campaign performance and understanding the impact of specific adjustments. Breakdown by device shows performance across different device types (e.g., mobile, desktop) but not campaign changes. Breakdown by creative analyzes the performance of individual ad creatives. Audience details provides insights into the demographics and characteristics of your target audience. None of these options track campaign modifications.
