Users reporting cloud synching not working

Hello, I have an app on the store and as of today, users are reporting that cards they collect are no longer syncing with iCloud. I haven't updated my app in about three weeks and the code hasn't changed. The app syncs correctly in the development build but not the release.

When I log in to the CloudKit Dashboard the Dev and Production Schema are correct.

What can I do?
