SceneManager.LoadSceneAsync skips from 0 to 0.9

Im loading a scene asynchronously with the following code:

Code (CSharp):

1.        
2.         AsyncOperation asyncOperation = SceneManager.LoadSceneAsync(levelName);
3.         asyncOperation.allowSceneActivation = false;
4.  
5.         while (!asyncOperation.isDone) {
6.             Debug.Log("Progress: " + asyncOperation.progress);
7.  
8.             if (asyncOperation.progress >= 0.9F) {
9.                 if (Input.GetKeyDown(KeyCode.F)) {
10.                     asyncOperation.allowSceneActivation = true;
11.                 }
12.             }
13.             yield return null;
14.         }
15.  

And this is what is printed:
Progress: 0
Progress: 0.9

So it is skipping from 0 to 90%

Why is this happening?

Thanks in advance for any help

 

Without knowing more specifics, it just sounds like the scene is loading extremely quickly, and halting at 0.9 per the documentation:

 

Maybe this?

Code (CSharp):

1. //Note: The progress may look like it goes straight to 100% if your Scene doesn’t have a lot to load.
