When you do, you can change the ticket’s status to resolved from the Ticket Properties section.
If you’d like to add a note summarizing the ticket resolution, you can mark the ticket as resolved while saving the note. Click on the arrow next to the Add Private/Public Note button and click on Add and set as resolved.
