I can not find solution after 2 days of experiments.
What it the problem :
I need to download Scene that is marked as Addressable in the background, while player plays other level.
Because my scenes are about 30-50mb it is not desirable for me to make players wait every time.
I need to download scene like a plain Addressables gameobject, that can be loaded after, somewhere in game, but it is already downloaded on mobile and is ready to use.
It’s a separate API for scenes. You can also call Addressables.DownloadDependenciesAsync(address) to just download in the background without loading into memory, then call LoadSceneAsync when you need it.
