Huge Time Lag of Addressables Package Method in Unity Engine

Question

within the unity project We are managing asset bundles using addressable packages.

However, there is a huge time lag when getting the download size using Addressables.GetDownloadSizeAsync(string).

Does this happen if the number of bundles managed is large? If it does, is there any way to fix it?

Currently, one label manages about 300 bundles.

// Asset Bundles Download Size
AsyncOperationHandle<long> getDownloadSize = Addressables.GetDownloadSizeAsync(BundleManager.GetInstance.DownloadKey);
return getDownloadSize;
