Váš kolega vytvoril v službe Display & Video 360 riadkovú položku pre klientovu kampaň pre mobilný web a omylom ju zacielil na mobilné aplikácie. Zacielenie na mobilné aplikácie následne odstránil na úrovni objednávky vloženia, ale kampaň je stále zacielená na mobilné aplikácie. Prečo je to tak?

In Display & Video 360, targeting settings are hierarchical. Line item targeting is more specific than insertion order targeting. If a line item is initially set to target mobile apps, and then an attempt is made to remove this targeting at the insertion order level, the line item's existing, more specific targeting will override the broader insertion order setting. To correctly remove mobile app targeting, the change must be made directly at the line item level, as insertion order settings cannot override or modify an already defined, narrower line item target. The other options are incorrect because line item targeting can be adjusted at the line item level, targeting can be adjusted after line items are assigned, and insertion order targeting can influence line items if the line item doesn't have a conflicting, more specific setting.
