application.css is getting ignored by splunk

[vikas_gopal]

Hi Experts,

I want to add my custom style to my app. I have done some modifications in application.css in ($SPLUNK_HOME/etc/apps//appserver/static/) folder and I restart the web service then refresh browser but it did not reflect the changes to the app.
here is my nav code

Application.css code

/*
 * Top app banner section
 */
.AccountBar {
    background-image: url(/static/app/samples/samples_header.png);
    background-repeat: no-repeat;
    background-color: #79a60b;
    height: 140px;
}

.AccountBar .appLogo,
.AccountBar p.appName {
    display: none;
}

.AccountBar .accountBarItems {
    background-color: #000;
    opacity: .5;
    filter: alpha(opacity=50);
}

/*
 * view menu system
 */
.AppBar {
    font-family: Arial Black, Arial, sans-serif;
    font-size: 18px;
    font-variant: small-caps;
}

.AppBar a {
    color: #f3df00 !important;
}

.AppBar a:hover {
    color: #6ad7ff !important;
}

/*
 * Body content
 */
body {
    background-image: url(/static/app/samples/body_bg.png);
    background-repeat: repeat-x repeat-y;
}

Please suggest what else do I need to consider

Clear Splunk Web related cache after customization
If you've made changes to an app's static content while customizing Splunk Web, you can reload that content for all the users of your app using this URI: http://localhost:8000/_bump
The _bump endpoint clears out the Splunk Web related cached items in client browsers, allowing new static content to load.

I missed my nav code

<nav search_view="search" color="#65A637" stylesheet="application.css">
  <view name="dashboards" default='true' />
</nav>

I actually want to hide account bar
