I have a serious problem and need help. I finished selecting 4,129 photos for my next book and have had them in an album now for a couple weeks. They were selected from the 69,500 photos in my LR mobile files. Today I needed to send them to my editor. As I was trying to send the link the album vanished. I have checked on my imac and on another iPhone. They've gone. An enormous amount of work was invested in this. How can I recover the album?
