I have two AppleTV 4Ks. I like to use photos from my home computer (through Home Sharing) as the screensaver, which plays back during music playback or while the device is in pause. Ever since the new Aerial Screensaver was added, my AppleTVs periodically lose track of my preference and, ZAP, we're back looking at the Aerial screensaver (which IS beautiful, btw). Any ideas about why I have to repeatedly tell the ATV my screensaver preference?
