So there have been lots of posts around about published services not working for Lightroom and Facebook with general error messages that Lightroom can't connect. Having received an update for Lightroom Classic yesterday and having removed and reauthorised LR / FB publish services a message now pops up that Lightroom is officially discontinuing published services support for Facebook. Disappointing as the advantage of published services is not to have to export to jpg and upload to FB thus not having to have jpgs clogging up disk space. A bit disappointing to say the least! Maybe someone will develop a third party published service plugin.
