I was assigned to manage a mobile app project and the owner decided to use Jira. I think the software (Jira) is very confusing. I messed up with Roadmap and Board (in Next-gen project template using Kanban). I am not so familiar with agile development and the documentation or Get Started articles are not helpful. The software has little bugs such as overlapping calendar view and page sometimes not refresh correctly in different Chrome tab. Anyone use this kind of Project Management tool?
