When you connect your Facebook, you'll see a pop-up in Marpipe to choose the Ad Account, Facebook Page, and Instagram Page.
If your Facebook Ad Account doesn't show up, you will need to make sure you have full access in Facebook Business Settings.
If your Facebook Ad Account shows up and the Facebook Page doesn't show up, the Page & Ad Account are not yet linked. This means you'll need to create and publish one ad in Facebook Ads Manager with the Page in the ad (does not need to run).
If you Instagram Page doesn't show up, you'll need to link it to your Facebook Ad Account in Business Settings -> Instagram Accounts -> Connected Assets.
