This iOS 8 release is such a cluster ****.
Healthkit has now been disabled and apps that use them have disappeared from the App Store until Apple fixes a last minute issue.
iCloud Photo Library has been pulled from the GM and is now labeled Beta.
Continuity and SMS Relay have been delayed (probably until Yosemite launches).
iCloud Photo Drive isn't ready if you use corresponding apps on a Mac. Devs recommend you wait until Yosemite launches or you won't be able to access your data on your Mac, since it basically closes off.
Photos for iOS will work better once Yosemite version launches. But as have no, there's no way to get your photos to your computer wirelessly. I guess you can fall back on connecting your phone to the computer and do it the Pre Mobile Era.
So basically all the major features of the OS have been delayed for some reason or another. Apple should have delayed this a month.
It doesn't matter to me though. My iPhone 6 Plus won't arrive until sometime in November even though I had my order in 40 minutes after it going live, 35 of those minutes trying to get on the damn website. By then, all the bugs should be worked out and features fully functional since Yosemite will be out by then.
Apple really should have pushed harder to get iOS 8, Yosemite, and Photos app to launch all at the same time for a more seemless experience. The House of Apple is crumbling.
