Broken Yield and Delay (in 1.3.0+)

See original GitHub issue

I’ve updated to 1.3.1 using git/packages installation and whole project is broken. Something like:

private async void Awake()
    await Test(); //or Test().Forget();

async UniTask Test()
	Debug.Log( "1" );
	await UniTask.Delay(1);
	Debug.Log( "2" );
	await UniTask.Yield();
	Debug.Log( "3" );

Prints only “1”

Tried it in empty project and it’s fine there. Any ideas?

Same issue and the above solution did not solve my problem. Specifically I created an Initialization script with lowest script executing order (so it should run first) with below code:

    private async void Awake()
        var playerLoop = UnityEngine.LowLevel.PlayerLoop.GetCurrentPlayerLoop();
        PlayerLoopHelper.Initialize(ref playerLoop);
        print("UniTask initializing");
        await UniTask.DelayFrame(0);
        print("UniTask initialized");

Only the first print statement works.

Ye, I think Unity needs like a one frame to update its playerloop.
