The availability of schedule or device adjustments depends on the Google Ads bidding strategy. With compatible strategies, the field appears normally. With automated strategies, Google may hide the field, use the adjustment only for the strategy target, or allow only device exclusion.

When an adjustment is unavailable, use the schedule to turn off periods that do not convert or the option to stop delivery on a device. Check the strategy name shown on screen: Ads Editor displays only the options Google accepts for that campaign.
