Starting on October 16, 2024, Google will begin rolling out changes to search and display reporting.
As a result of this change, Google Ads Query Language (GAQL) queries for campaigns with an advertising_channel_type of SEARCH or DISPLAY will return a value of 0 for any metrics in that GAQL query when you include the fields segments.asset_interaction_target.asset or segments.asset_interaction_target.interaction_on_this_asset in the query.
