Understanding Sync Success

To see your updates on other devices, the app and the iCloud system must complete the synchronization process.

A successful sync occurs when:

1. A change you made on one device has been uploaded to the CloudKit server.
2. All other devices signed in to your iCloud account have downloaded and applied the change.

If changes from one device don't appear on another device within your expected timeframe, you need to assess whether it's actually a sync issue.
