I have a series of issues.
I have categories that should not be auto-shared and I have marked them so in the settings. However. If a writer saves a post (before publishing it) and forgets to add a category the post will check the SNAP-post-options "share to FB" and "share to Twitter".
Even if I manually uncheck the boxes and save the post again it automatically reverts to "checked" after the page reloads.
I have made sure "uncategorized" should not be shared already. Does nothing.
