Here’s a funny thing that happened to me. I guess this option has been in the Lightroom (Lr) app for iOS for a few years, but I only just discovered it by accident, which seems to be the only way anyone ever uses it. As best as I can tell, it isn’t available in Lr on Mac, Win, or Android, but if you are determined, you might be able to find it at lightroom.adobe.com. What I’m referring to is the menu option, Only show in Shared Photos, hidden in the 3-dot menu next to an album that is already enabled for sharing. This is it on an iPhone. What happened is that I didn’t even notice it, and fat-finger hit it...
