Lightroom CC 2015.2 does not import new images with "Synchronize folder" unless "Show import dialog before importing" is ticked and imported that way. It does show that there are X new images to import, but just gives "No photos or videos were found to import." dialog after pressing "Synchronize". Using Windows 10 and images are on a mapped network drive.This has worked fine with all previous versions dating back to LR 3 or so when I started using it and definitely still with 2015.1.1 yesterday.
