Hi, @Developer Tools Engineer
Some of my users have encountered issues related to CloudKit in the past week, including myself frequently encountering CKError.Code.serviceUnavailable. The tricky part is that some devices will encounter data inconsistency issues, with no errors reported, making it very difficult to debug. (It seems that records created by another device cannot be queried through CKQuery, not 100% confirmed.)
At present, I can only provide this information, but I can confirm that there have been some new issues with CloudKit's service in the past week. I don't know if it's useful to submit a FB in this situation. Do you have any suggestions?
