When is the best time to load an AdMob ad?

Greetings, I’m currently developing a game on mobile which I plan to release on the Google Play store. I primarily uses the “Rewarded Video” ad as to not annoy players.

So, I have two scenes:

  1. Gameplay scene.
  2. Result scene.

If I use an action to “load” a Rewarded Video ad on scene 1 (Gameplay), and then use an action to “show” the aforementioned Rewarded video ad on scene 2 (Result), will that work?

Personally, I’ve considered doing it as dreams. The player would have some exceedingly strange dreams. Maybe due to technology. Ot maybe for some strange, unexplained reason.

So, whenever the player goes to sleep, rests, heals, etc. Depending on what type of game it is, of course. Maybe you could do it as commercials, at every decent stopping point, like live tv, if nothing else. But I would suggest limiting the length if you use this method.

The reason I asked this was that if I load the Rewarded Video ad at the same scene as the showing, there will be a delay of 10-15 seconds of “loading the video ad” before showing the player the rewarded video.

While I want it to be immediate. Hence the different scenes technique.

I’m asking to ensure if the “load” rewarded video action works even if it is located on a different scene than the “show” rewarded video action.

Please help me.
