Apple’s iCloud service starts on or around Sept. 18. As discovered by iCloud customers, some apps that use iCloud to sync data between devices could no longer do so. Indeed, either the app no longer syncs or appears to have lost their data altogether. The apps, which just got an upgrade to iOS 7, otherwise functioned normally. However, they simply didn’t show any saved information or could not update or sync existing info.
Apple has a pretty good record with iCloud, but glitches such as this have become more commonplace. I suspect this will become a monthly, sometimes a weekly event, as the iCloud system becomes more stressed with more devices and users.
Retail-oriented clouds, such as iCloud, will experience a great deal of growth over the next several years. The more they experience issues such as this one, the more the public may delay subscribing.
