How does the reporting differ between the dashboard and campaign sections

Your dashboard offers you high-level reporting for your campaign activity, providing datapoints such as overall impressions, clicks and spend based on the campaign activity you are filtering by. Your dashboard also gives you a summary of active campaigns, those starting and ending soon, and any campaigns that still need creative loaded.

Your campaign section differs to this as it offers you a greater level of reporting and information about your campaigns, offering insight down to the creative or line item level.
