I'm upgrading our application from Marketing API v2.2 to work with v2.3. In v2.2 everything worked fine, but in v2.3 when I try to post unpublished post (with the same user) I get the following error:
(OAuthException - #200) (#200) The user hasn't authorized the application to perform this action
I use the page access token with the following permissions: read_stream, read_page_mailboxes, rsvp_event, ads_management, ads_read, read_insights, manage_notifications, manage_pages, publish_actions
I also tried to post with the user's accessToken but it didn't work either.
