A new tool bar has appearred after upgrading to Citrix Workspace App for ChromeOS 2402.
 

Prior to 2402, the old old tool bar was displayed.
 

To revert to the old tool bar, you can disable switchToNewToolbar setting on the configuration. The following is an example of JSON data:

{
	"settings": {
		"Value": {
			"settings_version": "1.0",
			"engine_settings": {
				"ui": {
					"toolbar": {
						"switchToNewToolbar": false
					}

				}
			}
		}
	}
}

Problem Cause

A new toolbar was introduced in Citrix Workspace App for ChromeOS version 2402. The feature hasn't been officially released yet. However, in some environments where enableLaunchDarkly is disabled, the feature is unintentionally activated.
