Hello.  
We want to use custom backgrounds and find out that [updateVirtualBackgroundList](https://marketplacefront.zoom.us/sdk/meeting/web/functions/ZoomMtg.updateVirtualBackgroundList.html) doesn’t work properly. [updateVirtualBackgroundList](https://marketplacefront.zoom.us/sdk/meeting/web/functions/ZoomMtg.updateVirtualBackgroundList.html) doesn’t work for fist time after second call it works.

Here code

```auto
async iniVideoBackground() {
        await this.updateZoomVirtualBackgroundList(); // not works
        await this.updateZoomVirtualBackgroundList(); // works
}

private async updateZoomVirtualBackgroundList() {
        const videoBackgrounds = await this.zoomVideoBackgroundHttpService.loadVideoBackgrounds();
        await this.zoomClient.updateVirtualBackgroundList(videoBackgrounds);
 }

```

We are using the Meeting Web SDK (“@zoom/meetingsdk”: “3.13.2”,) with the Component View embedded in our web application.

Add a small delay before the first call. It _‘might’_ fix it.
