Facebook app review for screenshot share

Hi all,

In our application we use FB.FeedShare in order to share screenshot on Facebook. We also use OpenGraph method FB.API for adding photos to "me/photos" after taking a screenshot in order to get picture URL, for example:

FB.API ("me/photos", Facebook.Unity.HttpMethod.POST, screenshotPostCallback, wwwForm).

It is clearly stated in their documentation (see link below, Examples section) that we need publish_actions permission for this. https://developers.facebook.com/docs/unity/reference/current/FB.API

However, Facebook developers rejected our request in AppReview twice with a following explanation: "publish_actions: Your app is using the Share plugin to share content to Facebook, so you don't need to submit for review. Publish_actions is only for posting through the Graph API. See our sharing docs for more info on plugins.".

Are we doing something wrong? Is there any other way to share screenshot without using FB.API method? If yes, how to get picture's URL since it is necessary for all sharing methods (FB.FeedShare, FB.ShareLink etc.)?

FYI: we use FacebookSDK Unity package version 7.8.0 (both for Android and iOS).
