I was a bit confused when I could import items from JIRA manually, and webhooks were working both way, but when I made a new issue in JIRA, it was not getting auto-imported. I read through lots of really long explanations about the need for "parent records", but the bottom line is that you guys are doing this via the manual import because we can define "release" on import.
I propose that you guys allow in the JIRA configuration to auto-designate a "parent record" when new issues are made in JIRA so that it's seamless and doesn't require another step.
In the meantime, I've just noted that I need to add a ticket to a version in JIRA before it shows up in Aha!, but I could see issues getting lost and causing issues. I can also see your users having issues with understanding this concept to use JIRA, so I think it'd aid in onboarding.
