I'm trying to tag a user (having its userid), with a Graph request made to a picture just uploaded to a Page Gallery.
Permissions I use in the app are: @"read_stream", @"offline_access", @"publish_stream", @"manage_pages",@"photo_upload",@"user_photos" and with a access_token to the session got from page_it?fields=access_token item (that works for picture upload in gallery).
And I use them to upload the photo to a Gallery on a Fan Page successfully.
When I try to tag the user with a graph request in the form:
POST to picture_id/tags with param: "to"->userid I get only facebookErrDomain error 10000 as if permissions are not right.
From API Documentation seems that only user_photos and publish_stream are required and no mention to page-galleries photo is made.
I'm quite clueless about this issue.
