So we (a team of 6) have Jira Cloud free plan but need more granularity on Roadmaps and for now can't afford the Premium plan for Advanced Roadmaps.
I thought to try a Gantt app and have just installed the BigGantt. However I'm having no succes in getting this up and running with our already existing project data. We have only one project approx 100 issues..
Question: where and how do I map BigGantt agains this existing project? I can't find any easily interpretable documentation and our project has only default settings.
