Hello,
I reviewed this topic (https://support.zendesk.com/hc/en-us/articles/229729947-How-to-use-JIRA-Filters-to-see-Zendesk-Tickets-in-JIRA), but it doesn't show me how to do what I need. We intentionally link ONE Zendesk ticket to ONE Jira issue. I want to find Jira issues that have NO linked Zendesk tickets. The following query does not work for me:
project = "my project" AND issuetype = "enhancement" AND "Zendesk Ticket Count" = 0 ORDER BY updated DESC
