I want to display the date a ticket was resolved on my customer’s Ticket View (/support/tickets for the customers) on the customer portal, so when they review their ticket, they can see exactly when the ticket was marked as Resolved (or Closed).

I have tried these placeholders, none of which have worked:

{{ ticket.resolved_on | short_day_with_time }}
{{ticket.closed_on | short_day_with_time }}
{{ticket.resolved_on}}
{{ticket.closed_on}}

I can’t find any Liquid placeholders for the fields available on the Ticket View of the Customer Portal. This one describes Ticket placeholders that can be added to a ticket reply/automation. Some work and some don’t.

In the perfect world, I could display when a ticket was Resolved for the customers and add a note (if it’s been closed for a long time) that says the ticket is old and they should open a new one.
