allowSceneActivation on LoadSceneAsync not working sometimes

News & General Discussion

Below is the code I’m using on my EULA screen to preload my game. I want to wait until the user clicks the accept button on the EULA before switching to the game scene. What’s weird is if I start the LoadYourAsyncScene coroutine in the Awake function it will ignore the allowSceneActivation = false and it will switch scenes as soon as it is finished loading. However if I use a coroutine to wait a second or two before beginning the LoadYourAsyncScene it will work like I expect and wait until the accept button is pressed. Am I doing something wrong here or is this a bug?

IEnumerator LoadYourAsyncScene()
    {
        asyncLoad = SceneManager.LoadSceneAsync(scene);
        asyncLoad.allowSceneActivation = false;

        // Wait until the asynchronous scene fully loads
        while (!asyncLoad.isDone)
        {

            // scene has loaded as much as possible, the last 10% can't be multi-threaded
            if (changeSceneNow)
            {
                asyncLoad.allowSceneActivation = true;
            }

            yield return null;
        }
       
    }
public void ChangeSceneNow()
{
    changeSceneNow = true;
}

What happens if you use Start rather than Awake?

you have to wait that long?
i have the same problem, zero feedback from unity which indicates that nobody there knows, or that those who know are pushing yet another way of doing this very simple task
