Bug No Events are send OnApplicationQuit on Windows Build

I have a couple of custom events that are fired OnApplicationQuit.
It works fine in the Editor, my custom events and "gameEnded" are fired when I end playmode.
In Windows Builds I get the Analytics debugs for my custom evetns and "gameEnded":
Recorded event gameEnded at 2022-12-14 10:50:28.188 +01:00 (UTC)
Serializing event gameEnded for dispatch...

But the debug
Uploading events...
Events uploaded successfully!
is missing.

In WebGL I managed to get my custom events fired, when the browser tab is closed, but the "gameEnded" event is also never fired.

Is there a special trick to get those events? Or is is just a bug?

 

As I saw it, The events are send out via a webrequest, which is never callled, when the application quits.

So I made a workaround like this:

Code (CSharp):

1. void Start()
2. {        
3.      Application.wantsToQuit += WantsToQuit;
4.    
5. }
6.  
7. private bool WantsToQuit()
8. {
9.     if (sendingQuitAppsComplete)
10.         return true;
11.  
12.    StartCoroutine(DelayQuitCoroutine());
13.    return false;
14. }
15.  
16. private IEnumerator DelayQuitCoroutine()
17. {
18.    //send out custom events here
19.    //show some kind of "application is quitting"
20.    yield return new WaitForSeconds(1f);
21.    sendingQuitAppsComplete = true;  
22.    Application.Quit();
23. }

I basically delay the quitting of the application by one second.
This gives the analytics system enough time to send the gameEnded. Or at least my custom events are send then.

 

I looked into it again.
The Unity event "gameEnded" is still not send (not even after restarting the app). But my custom events are, which was good enough for my purpose.
