The launch of optimized targeting and deprecation of targeting expansion for display, video, and audio line items in Display & Video 360 have been postponed. Optimized targeting was previously announced to gradually launch for all Display & Video 360 partners from November 7 to November 9, 2022.

The changes in Display & Video 360 API behavior that were previously announced have also been postponed. The targetingExpansion field in the LineItem resource will continue to represent the targeting expansion feature.

We will announce a new date for these changes at a later date.
