I'm trying to use JIRA portfolio for release and macro planning in my project. One of the first troubles I've encountered is that the Sprint dates in the portfolio are off.
In the screenshot bellow, how can I change the sprint name? Cause it's Sprint 30something for me, how can I change the dates of sprint start/sprint end? We're using a 2 week cycle with the sprint starting on every second Wednesday.
