FileSystemWatcher does not inform about events on Samba share

Question

I use the FileSystemWatcher in my C# application and this application runs as a Windows Service on my server. The watchers path is a Samba share from another network. The application works totally fine when the folder path of the watcher is a folder on the Server, but with the shared folder no events are raised - I need to be informed when a file is created in the folder, then I move it to another one, rename it, read it and so on. (I also tried the watcher.Changed event but nothing is happening there either)

I found a similar question here: FileSystemWatcher with Samba on Linux

Does anybody know if the FSW has still problems with Samba-shared folders? I already tried to use a StreamReader and StreamWriter to test if I even have access to the shared folder - this works without any problems. I also thought about resetting the EnableRaisingEvents to true if the FSW "breaks" (like it is mentioned in the question above) but I am a bit confused how to even find out if it broke - because I don't get an error, it just does nothing at all.

This is a part of my watcher class, it runs as a BackgroundService:

protected override Task ExecuteAsync(CancellationToken stoppingToken)
{
    Initialize();
    TestAccessability();
    RunFileWatcher();
    return Task.CompletedTask;
}

private void TestAccessability()
{
    // Get the directories currently on the shared drive.
    DirectoryInfo[] sDirs = new DirectoryInfo(@"\\10.18.249.8\halit4ind$").GetDirectories();

    // Write each directory name to a file.
    using (StreamWriter sw = new StreamWriter(importPath + "\\SDriveDirs.txt"))
    {
        foreach (DirectoryInfo dir in sDirs)
        {
            sw.WriteLine(dir.Name);
        }
    }

    // Read and show each line from the file.
    string line = "";
    using (StreamReader sr = new StreamReader(importPath + "\\SDriveDirs.txt"))
    {
        while ((line = sr.ReadLine()) != null)
        {
            Console.WriteLine(line);
        }
    }
}

private void RunFileWatcher()
{
    logger.LogInformation($"RunFileWatcher watching path {importPath}");
    watcher = new FileSystemWatcher
    {
        Path = @importPath,
        Filter = "*.csv"
    };

    watcher.Created += OnCreated;
    watcher.Changed += OnCreated;
    watcher.EnableRaisingEvents = true;
}

private void OnCreated(object source, FileSystemEventArgs e)
{
    logger.LogInformation($"File {e.FullPath} created/changed - Type: {e.ChangeType}");
    if (e.ChangeType == WatcherChangeTypes.Created)
    {
        var newFilename = TryMoveFileToWork(e.Name);
        MoveFileToArchiv(newFilename);
    }
}

This is the output I get in the console (I tried creating a file in \10.18.249.8\halit4ind$\Outbox but nothing happens):
