Only currently active, or currently running, campaigns can be imported into AdEspresso.
Navigate to your Facebook ad accounts page in AdEspresso to ensure that importing is enabled for each of your ad accounts. Under Import Active Campaigns, the button should be green and toggled to Yes for each account.
If importing is enabled, double-check that your active campaigns on Facebook are published with that specific ad account. Your campaigns may be using different ad accounts that haven't been connected to AdEspresso yet.
We cannot import campaigns that have completed adsets.
