CKSubscriptionOptionsFiresOnRecordUpdate 类型的 CKSubscription 不起作用

Question

我使用以下代码设置了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，我会在添加新记录时收到通知，但在更新现有记录时我从未收到通知。

我已尝试从 CloudKit 仪表板和登录同一帐户的另一台设备更新记录。

我正在 iOS 9 beta 5 上进行测试。

这是一个已知的错误，更新通知不起作用。
