Some users have reported experiencing App Store issues in both the iOS and Mac stores with apps not finishing a download or not updating properly.
Some users are reporting obtuse error messages, like the one above, whereas others are simply left with paused downloads on their iOS and Mac devices.
Twitter reports of the issues began surfacing around 9:30AM Eastern time. Not everyone is experiencing the problem, and it doesn’t appear to be limited to iOS 8 or the Yosemite Beta. (MacTrast tried both the Mac and iOS App Stores on our computers and devices, and everything appeared to work.)
Apple hasn’t yet updated their system status page to acknowledge any ongoing issues. We’ll keep you posted.
