Fully knowing iCloud Photos would not work, I enabled it anyway a few weeks back. I even paid for some extra storage. But when I open Photos on iOS I have a hundreds of blank photos. The thumbnails are missing and when clicking them, they start downloading to 25% and then just stop. (I'm amazed they actually added a little progress indicator. Never expected them to do that.) But what's the point in having your pictures in the cloud if you cannot see them?? It's been 3 weeks so I assume no syncing is going on anymore. On OS X (my master library), everything is uploaded. I'm more mad at myself than at Apple as I predicted these issues here several months ago. Actually, reading them back, I was spot on But instead of using Dropbox I'm now considering Flickr as it offers 100GB for free. Am I the only one with this problem? Or maybe I should wait for OS X 10.10.4 and iOS 8.4. But it goes to show that Apple really is unreliable when it comes to services.
