An advertiser working in Display & Video 360 created a line item for their mobile web campaign and accidentally targeted mobile in-app. The mobile in-app targeting was quickly removed at the insertion order level, but the campaign continues to target mobile in-app. What is the issue here?

  • You can’t modify targeting once the campaign has line items assigned.
  • You can’t modify insertion order targeting at the line item level.
  • You can’t modify targeting for mobile in-app inventory.
  • You can’t modify existing line item targeting at the insertion order level.
