The first time you create a lead ad for a Page, you will be prompted to accept Facebook's lead ad terms of service with that Page.
If AdEspresso prompts you to accept the terms of service again even after you've already done it, this is a known issue caused by cached data, where the system doesn't recognize that the terms of service have been accepted.
Fortunately, this a one time permissions request, so once it is fixed you won't encounter it ever again. There are two workarounds to the issue:
- Save a draft of your campaign, and then refresh the page using Command+Shift+R or Ctrl+F5 to refresh while bypassing your cache.
- If that doesn't work, save your campaign as a draft, and then you can just wait a while for the system to automatically do a new check.
