Hi,

I’m facing slow loading of my map data. After debugging I found that my code is entering OnInitialized method 3 times which restart the loading of my data 3 times.  
Can you please help me with that?  
Thanks

```
 protected override System.Threading.Tasks.Task OnInitializedAsync()
 {
     osmLayers = new GeoCollection<LayerBase>();
     editingLayers = new GeoCollection<LayerBase>();
     highlightedFeaturesLayers = new GeoCollection<LayerBase>();

     LoadLayers();

     return base.OnInitializedAsync();
 }
```

Hi,

I couldn’t recreate the issue, OnInitializedAsync is only hit once on my side. Can you comment out the code in OnInitializedAsync and see if it helps?

```
protected override Task OnInitializedAsync()
{
    return base.OnInitializedAsync();
}

```

If it still has the issue, just keep simplifying the code in your project until it works to debug it.

Thanks,  
Ben
