Symptoms

Users in Jira are not able to assign issues to other users. There is no "Assign" button showing up on the screen:

Normally, there should be an Assign button as illustrated below:

Environment

Jira Server/Data Center on any version from 8.0.0.

Diagnosis

• The Permission Helper from Jira (accessible via the page ⚙ > System > Permission Helper) shows that the user has all the right permissions needed to assign issues:
  
• The Assignee field is also not showing up on the View issue screen, in the People Panel:
  
• Check the Field Configuration associated to the project the issue belongs to (via the page ⚙ > Issues > Field Configuration), and notice that the Assignee field is configured to be Hidden:
  

Cause

The reason for the problem is that the Assignee field is hidden from the field configuration.

Resolution

• Navigate to the Field Configuration page

• Select the field configuration corresponding to the project

• Look for the Assignee field, and configure it to not be hidden

You should be able to see the Assign button in the screen after performing this.
