For some of my maps, the Gantt Pro, even when I hit it, it does not show up. For other maps it does. I notice that those which do no show up have bigger file size. Is there any limitation on file size for this functionality?
No limit on file size, but there are potential issues with specific combinations of milestones and dependency types that can interfere with Gantt Pro charts. If you are able to share a map that does not load, I would be glad to take an unofficial look. (nick aaattt harportconsulting.com)
