My App is in the App Store, and synced well between iOS devices with the same iCloud account. But after adding a new attribute to an entity 2 weeks ago, the CloudKit stopped syncing. I checked the Cloudkit console, and can't find the new attribute there! I don't know Why. Actually this attribute already works well in the newest version of my App downloaded form App store. Then I chose to deploy schema changes, but there are no changes to deploy! So how to deploy the new change? and how to make the iCloud syncing work again? Thanks!
