After setting up the new Photos app in 10.10.3 I turned on iCloud Photos. The next day I deleted a few hundred photos in Photos on my mac, now they do not show in Photos BUT they still show on my iPhone and on icloud.com Is there an option with iCloud Photos to sync after you have deleted photos from a device? When I was deleting in Photos a message did appear everytime I deleted saying 'This photo will be deleted from all your devices' but that doesn't appear to be the case. The only thing I can think that has prevented it from syncing is that since turning iCloud Photos on my 2,000 ish photos are still uploading after 3 days? Do you think after the uploading is complete it may then sync and delete these photos from all my devices?
