I'm trying to submit my app for review with publish_action. I keep getting the following error: "It looks like you haven't made any API requests to access content with the publish_actions permission in the last 30 days." I'm publishing posts to the users' feed with Facebook SDK for Unity.: FB.Feed(link: LinkToApp); I've filled all the necessary fields. I posted both from the Graph and from an iOS device and I still get the same error when I try to submit for review. What is missing?
