When you connected TrafficGuard's Meta app to your Facebook portfolio, through Facebook Login for Business, this specialized login flow allowed TrafficGuard to access specific assets within your Meta Business Portfolio that you own or are assigned to, such as Pages, Ad Accounts, and Catalogs.
If you need to remove a partner, such as TrafficGuard, from your Meta business portfolio, follow these steps:
Access Business settings: Navigate to Business settings in your Meta Business Manager or Settings in Meta Business Suite.
Go to Partners: In the settings menu, find and select Users, then click on Partners.
Select and remove: Choose the partner you wish to remove from the list. Click on "Options" (which may appear as three dots or a gear icon), then select "Remove from business portfolio".
Confirm: Confirm your decision when prompted. This action will revoke their access to your business portfolio and all its associated assets.
Note: Only individuals with full control over the business portfolio have the authority to remove partners.
