According to this page: https://confluence.atlassian.com/jirasoftwarecloud/transitioning-an-issue-777002790.html
... I should be seeing something like this: 
when dragging a card from one column onto another (scrum board)
However, I don't see any (in fact, nothing happens)
I don't think it's a permissions issue since I have another board where this seems to work (although in that one I'm mapping just one status to one column)
I've also verified that "transition issue" is enabled at an Application level.
Can you help me sort this out?
