We have one premium license and the issue is that the feature assignee cannot be set as a dev when it goes to JIRA as Assignee only users that have no license cannot be set up in Aha. I want to be able to at least set up (or have JIRA send back and Aha accept) feature assignees that are not in Aha
This is becoming a big deal for us as well.
I'm running into the same problem here. For now I'm disabling the integration of Assignee via the Jira 2.0 integration, but I would really love to be able to turn it back on.
