The Campaigns view currently works in conjunction with companies. Under each company, you’ll be able to find the Saved Views available to you (ones created by you, or shared to you by someone else). You’ll also be able to customize or build new views based on the advertising accounts assigned to the company.
In short, companies define which:
- Accounts you will be able to see and use in your saved views
- Conversions you will have available (based on your accounts, apps and integrations connected)
- Custom conversions you can use (these are defined per company)
When sharing any views, you will be sharing the views to any Users with access to the same company.
As of now, you will only be able to build reports across accounts within the same company.
