[Question] Yield FixedUpdate And Update

[stnaw]

Why is it that when setting FixedUpdate and Update to different frame rates, the execution time of await UniTask.Yield(PlayerLoopTiming.FixedUpdate) and await UniTask.Yield(PlayerLoopTiming.Update) is the same? It seems to rely on the Update frame rate.

I'm hitting what I assume is a related issue right now.

It appears that the following won't run during physics frames (FixedUpdate) if seconds is less than the time to the next draw frame, but that it will run during the next draw frame (Update):
await UniTask.Delay(TimeSpan.FromSeconds(seconds), DelayType.DeltaTime, PlayerLoopTiming.FixedUpdate);

Repeating this call through an attached Debugger makes me wait until the next Draw Frame in Unity, instead of a Physics Frame like I would expect.
I looked at DelayType for something like DelayType.FixedDeltaTime, but that isn't an option.

Is it accurate to say that UniTask.Delay supports resolving UniTasks during FixedUpdate, but not updating UniTasks on FixedUpdate?

Edit: Just saw this issue, appears to confirm UniTask updates on draw frames, and won't on physics frames. Am I reading this correct? #377
