This issue concerns the plugin "Agile User Story Map".
When I try to drag a story from one epic to another, the map reflects this change, but the epic link in the issue is not actually updated. So when I reload the view, the story is back in its original epic. There's no toast that says 'successfully updated epic link' like it usually appears when you change anything else in an issue.
We're using a vanilla JIRA installation with JIRA Agile. The project uses the default Kanban project template.
Any help? Thanks!
