This question is in reference to Atlassian Documentation: Adding an Issue to an Epic
I don't have an "Agile" link with a drop-down in the top navigaition bar, so can't do this by viewing the issue/story in JIRA (last section on this page)
That tells us that you don't have access to JIRA Software. Either you're using Core, or, more likely, your account is only set up to log into Core (and/or Service Desk). As an admin check the application access your account has.
