This update is really important, and I believe is also quite unique for QA management tools overall:
From now on, you can create more than just one 2-way integration on your Account!
If you go to Account Setttings->Integrations, you can see that the “Create a new 2-way integration” button doesn’t disappear anymore once you establish one integration - it’s still there!
You can add a new integration with the same Bug Tracker but other instance - for example, two different Jira Servers, or different bug trackers.
Now when it’s time to connect the integration on a Project level, you will be shown which 2-way integrations exist on Account level, and will allow you to choose each of them:
Enjoy the new feature and new opportunities that it opens!
