Proper way to load scenes from remote

Hi,
In my mobile android project 10+ scenes (size 100±50mb) and i want client to load/update them from remote server on game starts.

I can see client creation pipeline like this:

1. Override player version to 1 (in AddressableAssetSettings -> General)
2. Create nonStatic(2*) group for each scene
groupA_nonStatic
- sceneA
groupB_nonStatic
- sceneB
…
3. Start “Build player content”
4. Send builded hash, catalog and bundles with overridden version 1 to remote server.
5. Build game .APK


So now new client will expect bundles with version 1 on remote server.

In case if I had change sceneA and need to update it:

1. Start “Build player content”
2. Send builded hash, catalog and bundles with overridden version 1 to remote server.

What I imagine happens on client’s device in result:

groupA_nonStatic(old) <- not referenced and will be removed from device cache.(3*)
- sceneA <- not referenced with new catalog
groupB_nonStatic <- stays as it was
- sceneB <- not changed
…
groupA_nonStatic(new) <- now it’s referenced for all clients with any game build version which expects bundles version 1.
- sceneA

Here is my general questions:
1. Was my thoughts correct? Is it proper way to handle my assets for device cache memory management?
2*. Static or nonStatic group - I suppose it doesn’t matter in my case? I mean if create group for each asset.
3*. When not referenced groups will be cleaned up?

P.S. Your work inspires, thanks in advance

 

The scenes on remote have failed to load from S3 buckets in build , but work in editor.
