Your colleague created a line item in Display&Video 360 for their client'smobileweb campaign and targeted mobile in-app by mistake.They went in and removed the mobile in-app targeting at the insertion order level,but the campaign is still targeting mobile in-app.Why could this be happening?

Youcan't modify existing line item targeting at the insertion order level.If your colleague mistakenly targeted mobilein-app at the line item level and attempted to remove it at the insertion order level,the changes may not take effect.In Display&Video360,targeting modifications made at the insertion order level apply to newline items created within that insertion order but may not retroactively alter the targeting of existing line items.To correct the error,your colleague should directly adjust the targeting settings within the specific line item where the mistake occurred,ensuring that the correct targeting options are selected to align with the campaign's objectives.
