Facebook Pixel is not showing
Pixel 101
If you have your Pixel set up in your Facebook Business Manager but it's not appearing while selecting a Conversion Goal, it's possibly because it's not connected to the Ad Account.
To connect the Pixel to the Ad Account you should:
- Head over to Business Manager and tap on Settings
https://business.facebook.com/settings - Select Data Sources from the left menu and then click on Data sets
- Click on Assign Assets
- Select the correct Ad account

After following these steps, you might need to reconnect facebook on the Connect Platforms tab to refresh the data connection.
