Apple has issued a fix for a bug that prevents data from third-party apps from syncing properly with iCloud.
The Cupertino, California-based technology giant did not reveal what the problem was but in a post on its forum, it said the errors were akin to "request-throttling that may be affecting a specific user, or the container as a whole".
It also blamed an "underlying issue" that "caused an elevated number of these error responses to be returned to your CloudKit apps in certain situations".
Regarding the recent iCloud sync issue, I received a very kind and detailed response from Apple indicating that the underlying issue causing the 503 errors/sync failures has been fixed! (Please share!)

App developers had been facing the problem since November, with Apple not acknowledging the bug until now. The bug led to a lot of users seeing the error message, "Request failed with HTTP status code 503," which developers feared, would result in a negative perception of their apps in the eyes of consumers.
