    {
        case UIStatus.Hidden:
            fileUpdateRequest.Status = FileUpdateStatus.UserInputNeeded;
            fileUpdateRequestDeferral.Complete();
            break;
        case UIStatus.Visible:
            break;
        case UIStatus.Unavailable:
            fileUpdateRequest.Status = FileUpdateStatus.Failed;
            fileUpdateRequestDeferral.Complete();
            break;
    }
}
