CloudKit Stopped Syncing after adding a new Attribute

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!

Run your app in the Development environment. Then go into the CloudKit Dashboard, switch to Development environment and look for your new attribute there. Then if all is well, deploy it to the Production environment.

Right! Just adding the attribute isn’t enough. You need to save data for the attribute. Please mark my response with the green acceptance.
