Real time data in Google Analytics is now showing

Question

I have a problem with real-time data using Google Analytics v3.1 Users, events, e-commerce is working fine, but real-time features like screen tracking is not showing.

Here is GAI initialiser code:

  [GAI sharedInstance].trackUncaughtExceptions = YES;

  [GAI sharedInstance].dispatchInterval = 20;

  [[[GAI sharedInstance] logger] setLogLevel:kGAILogLevelVerbose];

  [[GAI sharedInstance] trackerWithTrackingId:@"MY-TRACK-ID"];

Then I inherited all my view controllers from GAITrackedViewController via subclassing all controllers from BaseViewController : GAITrackedViewController. Then I set screen names for all needed controllers in - (void) viewDidLoad method like

- (void)viewDidLoad {
    [super viewDidLoad];
    self.screenName = @"Some Screen Name";
}

No error showing, data dispatches successfully(I suppose). Also I tried to put this line to - (void)viewWillAppear: method, but nothing happened. Tracking ID is absolutely correct, cause another features is working fine.

Also I tried to send screens manually:

id tracker = [[GAI sharedInstance] defaultTracker];

// This screen name value will remain set on the tracker and sent with
// hits until it is set to a new value or to nil.
[tracker set:kGAIScreenName
       value:@"Some screen name"];

[tracker send:[[GAIDictionaryBuilder createAppView] build]];

And the same result. Even if manually call dispatch method.

I notice strange thing that self.tracker instance in each my view controller is nil, but [[GAI sharedInstance] defaultTracker] returns tracker value, as expected.

Thanks in advance!
