So while I'm invested on the Android side of things when it comes to my phone and my watch, I am part of the Apple ecosystem when it comes to tablets (Air 2, Mini 3) and my iPod Touch 6th Gen. I use Google Photos primarily to back up all my photos on my Android phone, but the app on iOS isn't as feature-rich as Android, and this goes for a few other apps like Plex as well. So what I decided to do is pay $0.99 to try out how I like iCloud and see if it was a worthy investment of $12 / year, particularly because I would then have everything sync to my iOS tablets with a little extra leg work. I decided to work from my desktop (better upload speeds, organization, etc.) and I logged on to iCloud.com --> Photos to begin my task of uploading the contents of folders to the appropriately labelled and newly created albums. For example: The contents of Disneyland Aug 2015 would go into an album titled "Disneyland Aug 2015"; and that way I don't have to add the images into an album after uploading. After I uploaded most of them, I switched over to my iOS devices, turned on iCloud Photo Library, set it so it 'optimizes the library' instead of downloading the originals and waited... I wasn't too happy, and I'm not sure if I'm doing something wrong. 1) iPod Touch takes forever to download the pictures. Granted it's only a 16 GB model, but I have about 1.5 GB free. Compared to my Air 2, I have about 17k photos out of the 21k on the tablet. 2) I try to open one of the non-downloaded images (white screen, with a cloud on the bottom right). The cloud changes into a loading circle, but stops 1/4 of the way through. I leave it on for 5, 10 minutes and it's still there. It's not downloading or anything. 3) Mini 3 doesn't want to update at all. I have the settings correct, the proper iCloud account, etc. but it doesn't want to recognize the albums or anything. 4) The albums on the Air 2 are correct, but some of the images inside the albums are missing. Say an album X had 17 images uploaded on iCloud.com / it shows up as 17 images on iCloud.com; well, I only got 1-2 images on my Air 2. The images download much quicker on the Air 2 though. I have a pretty decent internet connection (150/50), so I'm confused if the hardware on the Touch is the reason for it's slowness, or if this is a general iCloud issue. I do like the iOS integration, which is why I decided to purchase additional iCloud storage and decided against using Google Photos only. I'm new to iCloud Photo Library, and while I have tried to read as much as I can, I'm just lost right now. I'm wondering if this takes a few days to 'settle in', or something. I wouldn't imagine that to be the case, but who knows. Thanks!
