We created a kanban board and now want to be able to sort based on summary. This does work for the kanban backlog, but not for the board itself?
Does anybody know what other settings need to be done?
Ok, I was only looking at the problem with that specific query.
You can't do what I think you are trying to do because you can't do "Order by Summary, but keep all the subtasks under their parents" (without some code anyway - you can usually spot a Jira I've configured because it will have a scripted "parent" field to allow such grouping).
The only thing I can think of doing on your board is to have a board filter that includes both standard and sub-tasks, but then have a "quick filter" for "issuetype in standardIssueTypes". That will let you at least toggle the view of them on and off in the board.
