Google Firebase and Unity (C#): Unable to download png from bucket

Specs

 Unity editor version:       2018.2.8f1
 Firebase Unity SDK version: 5.5.0
 Additional SDKs:            SimpleFirebaseUnity
 Developing on:              Mac
 Export Platform:            Android

Issue

I'm having troubles setting up a system to download pictures from storage. I'm not an expert in databases, but I wanted to give it try, just to learn how it is done. I found Firebase very useful to store metadata on the real-time database and easy to approach even for an entry level coder like me.

The problem is that I'm trying to download a .png file from a folder in storage, but I can't manage to find if the file is actually downloaded or if it's just lost in the process. I don't get any errors in the console, but when I open the folder in which the files should be, it's empty.

Thanks

Code

 private SimpleFirebaseUnity.Firebase firebaseDatabase;
 private FirebaseQueue firebaseQueue;
 private FirebaseStorage firebaseStorage;
 private StorageReference m_storage_ref;
 
 // Setup refernece to database and storage
 void SetupReferences()
 {
     // Get a reference to the database service, using SimpleFirebase plugin
     firebaseDatabase = SimpleFirebaseUnity.Firebase.CreateNew(FIREBASE_LINK, FIREBASE_SECRET);
 
     // Get a reference to the storage service, using the default Firebase App
     firebaseStorage = FirebaseStorage.DefaultInstance;
 
     // Create a storage reference from our storage service
     m_storage_ref = firebaseStorage.GetReferenceFromUrl(STORAGE_LINK);
 
     // Create a queue, using SimpleFirebase
     firebaseQueue = new FirebaseQueue(true, 3, 1f);
 }
 
 // ...
 
 IEnumerator DownloadImage(string address, string fileName)
 {
     var local_path = Application.persistentDataPath + THUMBNAILS_PATH;
     var content_ref = m_storage_ref.Child(THUMBNAILS_PATH + fileName + ".png");
 
     content_ref.GetFileAsync(local_path).ContinueWith(task => {
         if (!task.IsFaulted && !task.IsCanceled)
         {
             Debug.Log("File downloaded.");
         }
     });
 
     yield return null;
 }

I seem to be having an identical problem - did you figure it out?

Hi, did you find any way to fix the issue ? I also have a json file stored in firebase storage and I'm trying to download it. It works fine in unity editor but not in android. If you have any idea or solution regarding it please do let me know. Thanks
