I've a test installation of Lightroom 6.2.1 on a computer with Windows 7 Ultimate. In my workflow I synchronize photos from my NAS to a local disk and then use Lighroom's function "Synchronize folder" to import changed or new photos. Since 6.2.0 it doesn't work - "Synchronize folder" shows that there are 250 new photos, but following synchronization doesn't import any photo and writes "no videos of photos found to import". Photo files are mainly cr2 files from Canon 7D mark II.
Thanks, so I will wait with for 6.3
