Apple limits the number of ad campaigns per app on the ad network. You can create a maximum of 100 campaigns with targeting on iOS 14.5+ for each app in myTarget.
Each campaign targeting iOS 14.5+ is assigned an
Apple campaign ID - a number from 1 to 100. The ID will appear in the campaign settings after creation.
The app owner has access to all 100 Apple campaign IDs and can create 100 campaigns. The owner can pass part of the ID to their agents. If the agent is an Agency, then it can
transfer its campaigns to the Agency's client.
For example, the app owner has two agents: Agent 1 with the "Advertiser" account type and Agent 2 with the "Agency" account type. The owner passed 40 Apple campaign IDs to Agent 1 and 60 IDs to Agent 2.
Agent 1 can create 40 campaigns with targeting on iOS 14.5+. He is registered as an advertiser and therefore cannot pass on the IDs to anyone.
Agent 2 is registered as an Agency, so it can transfer the available IDs to its clients with the "Agency Client" accounts type.
