Great idea, great concept. However, this much awaited app has got the worst sync service I’ve ever seen. Simply doesn’t work well. I’ve been trying to sync both my iPhone and my iPad camera rolls to Lightroom and only occasionally does it work. There are three problems: (1) the app automatically syncs your device’s camera roll to a Lightroom local folder (whose location in your HD you sadly can’t chose); (2) the app automatically creates a smart folder for each device, so it’s totally redundant, since we have now, in Lightroom, two places for the same images; (3) the sync rarely works. I’ve done many tests and most of them have been unsuccessful so far; (4) now comes the REAL problem, which is the awful experience you’ll have if you want to delete your images. Now you’ll have to delete them from your mobile device, then you’ll have to delete them from the smart folder automatically created in your catalog, and then you’ll have to delete the images from the actual folder automatically created by Lightroom Mobile in your HD; (5) it gets worse, because when you delete the images from your local folder, they’re not deleted from the smart folder. I deleted images from the actual folder and from the device and they still stuck in the smart folder. Impossible to understand. Either it’s an error or a pretty bad taste for workflow efficiency. I know what to expect from Adobe. Unfortunately, Lightroom Mobile still remains at its draft stage. I regret having paid for it.
