Due to recent changes in the way Facebook is working with third-party developers, direct upload of photos and videos from desktop products to Facebook is no longer supported.
From Facebook documentation:
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.
This change is effective as of August 01, 2018.
You will no longer be able to upload photos to Facebook from Lightroom desktop apps - Lightroom (new), Lightroom Classic, and Lightroom CC 2015/Lightroom 6.
Any future API changes introduced by Facebook can impact the publish service again.
