How do I link issues across projects on Gantt Charts?

[Timothy Vile]

Is it possible to link issues across projects in Gantt Charts?

I have permission to link issues on both projects.

(In Gannt Charts) I can link issues in each project so long as both issues are in the same project. I am able "add" a link to an issue in the other project, but the link doesn't show up once the page is refreshed. 

I can add the cross-project link if I go to the issue directly (Issues tab). The cross-project link shows up on the issue page. But when I go back to Gannt Charts and look at the issue, the cross-project link doesn't show up. And Gannt charts isn't adjusting the chart links.

There are multiple Gannt Charts plugins. Can you provide a link to the one which you are using?
