  1. Resolution Note:

    The legacy input system (everything in UnityEngine.Input class) only supports a single Touch.Phase change per frame, because Thread.Sleep pauses the execution of a frame it's expected that only that last event will be returned.

    This issue will be resolved in the new input system where we'll have callbacks for all touch event.
