Horrible. I installed it, and started syncing my photos. Of course I quickly ran out of storage with my photos & videos. I tried deleting some photos from the cloud and it keeps deleting my original photos from my device! You can't remove or add permissions because it says "no permissions allowed and no permissions denied" wth. Now I'm trying to delete the cloud photos to free up space but can't without my originals being deleted. Everything worked fine on my phone before I installed this app!
