`yield return null` and `UniTask.Yield` are similar but different. `yield return null` always returns next frame but `UniTask.Yield` returns next called. That is, call `UniTask.Yield(PlayerLoopTiming.Update)` on `PreUpdate`, it returns same frame. `UniTask.NextFrame()` guarantees return next frame, you can expect this to behave exactly the same as `yield return null`. `yield return null` and `UniTask.Yield` are similar but different. `yield return null` always returns next frame but `UniTask.Yield` returns next called.

`AsyncOperation` is returned from native timing. For example, await `SceneManager.LoadSceneAsync` is returned from `EarlyUpdate.UpdatePreloading` and after being called, the loaded scene's `Start` is called from `EarlyUpdate.ScriptRunDelayedStartupFrame`. Also `await UnityWebRequest` is returned from `EarlyUpdate.ExecuteMainThreadJobs`. `AsyncOperation` is returned from native timing.

Also `await UnityWebRequest` is returned from `EarlyUpdate.ExecuteMainThreadJobs`.
In UniTask, await directly uses native timing, `WithCancellation` and `ToUniTask` use specified timing. This is usually not a particular problem, but with `LoadSceneAsync`, it causes a different order of Start and continuation after await. So it is recommended not to use `LoadSceneAsync.ToUniTask`.
