The reason why we disable this Facebook app on our app store is because Facebook already deprecated this user publish_actions permission, so user unable to automatically autopost their stream content in their Facebook user profile page, if the user would like to share their stream content to their Facebook profile page, they have to manually click the Facebook share dialog from the stream item.

Deprecation:

The publish_actions permission will be deprecated. This permission granted apps access to publish posts to Facebook as the logged in user. Apps created from today onwards will not have access to this permission. Apps created before today that have been previously approved to request publish_actions can continue to do so until August 1, 2018. No further apps will be approved to use publish_actions via app review. Developers currently utilizing publish_actions are encouraged to switch to Facebook's Share dialogs for web, iOS and Android.
