Last week, I have installed the BigGantt app into Jira. I have created a big roadmap and saved it. I used the new (Alpha version) for this, by clicking the icon on the left top when in a BigGantt project. However, when I want to go back to it today, it just stays on the loading screen for a few minutes and then says "Something went wrong - try to reload or contact Atlassion Support."
I already put the maximum loaded-tasks to a minimum, so it is not that - the normal version of BigGantt loads fast and without any problems. I also tried it in both Firefox and Chrome, but it doesn't work on any.
Does anybody have an idea what it could be?
