Google Tag Manager doesn't fire events to Google Analytics

Question

I'm using Xamarin.iOS and I have integrated TagManager using Google Analytics SDK (V3.10)

I can see in the logs that the request is sent to Google Analytics, but It is not displayed in the dashboard.

The same firing rules exits for both Android and iOS, which is always (true == true), and it works in Android great.

This is the code for the class TagManager in iOS:

public class IosTagManager : NSObject, ITagManager, ITAGContainerOpenerNotifier
{
    private TAGContainer _container;

    public IosTagManager() 
    {
        var tagManager = TAGManager.GetInstance;

        tagManager.Logger.SetLogLevel(TAGLoggerLogLevelType.Verbose);
        
        var containerId = "GTM-XXXX";
        
        TAGContainerOpener.OpenContainer(containerId, tagManager, TAGOpenType.PreferNonDefault, 2.0, this);
    }


    public void Push(string key, string data)
    {
        var dict = new NSDictionary("event", key, "screenName", data);

        TAGManager.GetInstance.DataLayer.Push(dict);
    }


    public void ContainerAvailable(TAGContainer container)
    {
        _container = container;
    }
}

This is the log from TagManager:

Answer 1

So after returning to work a day after I used the SDK, everything worked and all the data regarding iOS system is now been displayed in Analytics console without changing any code.

So it was a 24 hours waiting as stated in Google official link here

"If you have installed tracking and don't see data in your reports after 24 hours, you may have one or more of the following issues." ...
