Deleting photo on a device (iPad, Iphone at least) deletes them from the cloud. this makes it impossible to use the cloud as the on the go backup for your photos. i will travel for 6 month and i expect to have more photos on the iPad than it can store. thus i need to offload them to a cloud as i go. but i want to process them in LR as i travel and save them with all edits on the cloud for further processing on the desktop computer when i am back from my trip. I think it is such an obvious and natural usage case of the cloud service that i am surprised it has not been implemented yet. Do you expect such functionality within 4 months?.
