How to properly update assets from remote server in the launch scene?

Hi friends,

I have read and watched everyting I found about addressables but there is still something not clear for me.
My target is to check the bundle version hosted in the server and download the bundle if a new version exists.

Problem 1) How can I check the server version? I have played with Addressables.CheckForCatalogUpdates() and it always return 0. No matter Addressable group is static(Cannot change post release) or not. And also I didn't understand when and why should I set a group static.

Problem 2) Let's say I am in the Launch scene(the first scene in my game) and I did check and know that there is a bundle with new version on the server. I want to download the new bundle before moving to another scene to make everything ready. Is there a method for downloading a bundle? What I have seem so far is that you try to load an asset, if not cached, related bundle is downloaded from server. So basically, I want to download everthing new on the server beforehand.

Thanks!

 

static group allow you use Tools -> Check for content update restriction.
this tool make new group with changed resources to new bundle.

Addressables.CheckForCatalogUpdates();
Addressables.UpdateCatalogs();
before go to another scene - its check hash file on server and download new content then its needed.
