Not receiving CloudKit push notifications

I'm writing a small app that uses CloudKit. For some reason the app doesn't receive any notifications when there's a new record matching the query. Has anyone been able to get this feature to work?

I create new records in the app, but also in the CloudKit dashboard. The record is very simple, with a single integer field.

Create a record:

 CKRecord *record = [[CKRecord alloc] initWithRecordType:kSISCloudKitRecordTypeTest];
 record[@"value"] = @1;
 [self.publicDatabase saveRecord:record completionHandler:^(CKRecord *record, NSError *error)
  {
       // this call succeeds, no error.
  }];

Register for notifications:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [application registerForRemoteNotifications];
}

Create a subscription:

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"value = 1"];

CKSubscription *subscription = [[CKSubscription alloc]
                                initWithRecordType:kSISCloudKitRecordTypeTest
                                predicate:predicate
                                options:CKSubscriptionOptionsFiresOnRecordCreation];

CKNotificationInfo *notificationInfo = [CKNotificationInfo new];
notificationInfo.alertLocalizationKey = @"LOCAL_NOTIFICATION_KEY";
notificationInfo.soundName = @"Party.aiff";
notificationInfo.shouldBadge = YES;
subscription.notificationInfo = notificationInfo;

[self.publicDatabase saveSubscription:subscription
                    completionHandler:^(CKSubscription *subscription, NSError *error)
 {
     // this succeeds as well, at least the 1st time I run it.
     // on subsequent calls it returns an error "duplicate subscription", which is OK by me.
 }

After running the above code, and creating a new record in the dashboard, I expect this app delegate method to be called:

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    CKNotification *cloudKitNotification = [CKNotification notificationFromRemoteNotificationDictionary:userInfo];
    NSLog(@"cloudKitNotification: %@", cloudKitNotification);
}

However, it never gets called.

I am now receiving the notifications since Beta 3:

{
    aps =     {
    };
    ck =     {
        ce = 2;
        cid = "iCloud.com.domain.App";
        nid = "0b3ae470-d2c0-4f35-a817-12a899ee5964";
        qry =         {
            dbs = 2;
            fo = 1;
            rid = 88aee11ca88d4ecc45bf57c898b360c8e7e3d8bb;
            zid = "_defaultZone";
            zoid = "_defaultOwner";
        };
    };
}

Also, there’s a shouldSendContentAvailable property on CKNotificationInfo that makes it possible to receive the notifications in background – which also appears to work now (as of Beta 4).
