I\'m using NSUbiquitousKeyValueStore to store some app settings. My logic is: when I save data locally, I save it to NSUbiquitousKeyValueStore also as a backup. When I need
Conclusion
Temporary solution is: - call synchronize before get data from key-value store - to be sure it would work "turn off iCloud->Documents&Data - turn off and again on network - turn on Documents&Data", but also you should wait several minutes before iCloud downloads all needed data
Note: when app is installed and already worked (saved/loaded) with key-value store updates of iCloud data are pretty fast (7-15 sec), but when you reinstall the app it seems that icloud needs several minutes to actualize key-value store.
I'd be glad to hear your thoughts, because icloud looks like almost unusable feature. But I don't want to set up my own server to merely get the same functionality.
