I just signed up for Lightroom CC, Creative Cloud and the accompanying Lightroom App. Apparently no native support of LL app for Apple Airplay.
I then tried the Creative Cloud app, similar issue. Even worse, because now the sort order of my pictures is messed up. I was under the impression the Lightroom app was specifically designed to for Apple IOS. But it cannot display my photos on a Apple TV in full resolution and format? C'mon Adobe. Can this be true?
