    Dear,

    I have used the Addressables.LoadSceneAsync() and Addressables.UnloadSceneAsync() now.

    First Memory Snapshot
    -> Scenario
    1) Load Scene Additive (Scene A)

    Second Memory Snapshot
    -> Scenario
    1) Load Scene Additive (Scene A)
    2) Unload Scene (Scene A)
    3) Load Scene Additive (Scene B)
    4) Unload Scene (Scene B)
    5) Load Scene Additive (Scene A)

    Ideally, both Snapshots should have the same memory.
    However, as shown in the attached picture, the combined mesh is accumulated every time it goes to another scene.

    unity version : 2021.3.16f1
    addressables version : 1.19.19

    I used two functions below and solved it.

    Resources.UnloadUnusedAssets();
    GC.Collect();

    Thanks

    This looks like the they are embedded scene objects.
    When the scene loads, any embedded assets, like static batching, are a part of the scene.

    You would need to tell the scene unload options that you want to unload these embedded scene objects like so:
    Addressables.UnloadSceneAsync(m_SceneHandle, UnloadSceneOptions.UnloadAllEmbeddedSceneObjects);
