I realise this is not Aha's fault, but if we put the issue here with more info, users will be more likely to go to Jira to vote for the issue there.
Currently whenever someone comments on an issue in Jira, in appears in Aha as a comment from the person that made the integration between Jira and Aha. I think the same happens vice-versa. At the moment it gets very hard to track who is doing what between the two systems. I sometimes end up with 3 different names attached to an event.
This is due to a Jira limitation. JIRA does not allow you to create comments on behalf of anotheruser. To vote for this with Jira please go here: https://jira.atlassian.com/browse/JRA-35124
We can see the value of this feature as there can be confusion around who is creating comments. As noted, this is due to a JIRA limitation. We will mark as "unlikely to implement" for now, but will revisit in the future when this issue has been resolved.
