CKSubscription类型的CKSubscriptionOptionsFiresOnRecordUpdate不起作用

Question

我用以下代码设置了一个CKSubscription：

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"TRUEPREDICATE"];
CKSubscription *subscription = [[CKSubscription alloc] initWithRecordType:@"RecordTypeName"
                                                                 predicate:predicate
                                                            subscriptionID:@"Subscription1"
                                                                   options:CKSubscriptionOptionsFiresOnRecordCreation | CKSubscriptionOptionsFiresOnRecordUpdate];

CKDatabase *privateDatabase = [[CKContainer defaultContainer] privateCloudDatabase];
 [privateDatabase saveSubscription:subscription completionHandler:^(CKSubscription * _Nullable subscription, NSError * _Nullable error) {
     if (error) {
         NSLog(@"Failed to subscribe.");
     }
 }];

在application:didReceiveRemoteNotification:中，添加新记录时会收到通知，但在更新现有记录时，我从未收到通知。

我尝试从CloudKit仪表板和另一个登录到同一个帐户的设备中更新记录。

我正在测试iOS 9测试版5。

更新通知不起作用是已知的错误。
