Lightroom 2015 and Mobile for Android are set to sync automatically. I have 95 photos on my mobile, and 6 more have just been added. The 95 are showing on the desktop, and on the nameplate it is saying "syncing 96 photos" and only one of the new ones has shown up so far. It has been syncing for an hour. I have previously tried disabling and re-enabling syncing, disabling the virus/firewall scanner, exited LR and restarted, restarted the computer and each time it has been stuck in sync mode for ages. My broadband connection is 20Mb/s. How long should syncing be reasonably expected to take?
