The Batman movies have Atmos restored, but not the other titles yet.iTunes is such a clusterf***. I was noticing yesterday that a whole slew of titles no longer had the Dolby Atmos logo attached. I figured it was just a glitch with the listings, but I just now confirmed on my playback system that they no longer play back with Atmos. The three titles I checked were Rocketman, Batman '89, and Deadpool 2.
edit: add to that Batman Returns, Bohemian Rhapsody, and First Man
