Sitejet button is not visible on a domain

Symptoms

• The Sitejet Builder button and icon are not available in Domains > example.com > Dashboard
  
  
• Usage of Sitejet Builder is enabled for the Subscription
• The Sitejet Builder extension is installed and up to date
• Plesk version is 18.0.71 or higher

Cause

This is expected by design, because when a Sitejet website has never been published on this domain yet, the SiteJet Builder button is not expected in the Dashboard tab yet, but can be accessed in the Get Started tab:

Resolution

When you press the Create Website button via the Get Started tab and press Publish in Sitejet at least once, you will be able to see the Sitejet Builder button and icon in Domains > example.com > Dashboard
