Your customer,an advertising agency,wants to create automated rules in Search Ads 360 for all the campaigns associated with their agency--buttheycan't see all their campaigns.What's one reason this might be happening?

The correct answer is that some accounts are managed within manager accounts, and you have sub-manager account access. In Search Ads 360, access levels determine what you can view and manage. If campaigns are organized under a top-level manager account and you only have access to a sub-manager account, you will only see campaigns associated with that specific sub-manager account, not all campaigns under the main manager. The other options are incorrect because having sub-manager access to all accounts would grant visibility to all campaigns within those sub-managers. Campaign-level access, regardless of how accounts are managed, would restrict visibility to only the specific campaigns you have access to, not a broader set.
