To start your RMG approval you need an ad account connected. Follow these steps to find out how.
Go to Facebook Business Manager
Access Business Settings
Click on settings in the left sidebar.
Select Business Settings.
Navigate to Ad Accounts
Under the Accounts section on the left sidebar, click Ad Accounts.
Add an Ad Account
Click on the blue 'Add' button and choose one of the following:
Add an existing Ad Account (if you already own it)
Request Access to an Ad Account (if someone else owns it)
Create a new Ad Account (if you're starting fresh)
It's always best to start fresh, as it's the easiest, so if possible start fresh and fill out the info.
Enter Ad Account Details
If adding an existing account, enter the Ad Account ID (found in Ads Manager)
Confirm Ownership or Request Access
If you're adding an existing account, Facebook will verify ownership.
If you're requesting access, the owner must approve your request.
Save and Verify
Click Save, and you should see your Ad Account under Business Settings > Ad Accounts.
Please Note - Facebook might restrict your fresh ad account so they can confirm you are a real person. If this happens:
Press 'view my accounts'
Press 'request review'
On there, you should be able to provide some type of identification to prove you are a real person.
Wait up to 48 hours for a response from Facebook.
