Third Party PUN 2 : How to wait before loading a scene ?

I've been using PUN 1 a lot before and I'm on a new project, trying to switch to PUN 2.

However I seen that PhotonNetwork.LoadLevelAsync() doesn't exist anymore and is replaced by PhotonNetwork.LoadLevel() which is executed Asyncronously but isn't an AsyncOperation.

So I would like to know how could I make all players preload a scene before actually changing to it, like it was possible before by turning asyncOperation.allowSceneActivation to false.

 

I replied in our forum.
