next-gen epic with other (classic) projects issues

[Bastian Brodbeck]

Hello, 

I have a next-gen project with a roadmap and several epics in it.These epics can span multiple teams and projects in Jira.

Now I want to add issues from other projects (that can be classic) to these epics, but when I want to add them the next-gen epics do not show up.

How do I add issues from other projects to these next-gen epics?

you cannot add issues from Classic project to Epics of NG projects.

I also cannot add issues from other NG-projects. This makes the roadmap kinda limited as I do not find a way to see ALL roadmaps of ALL projects on the same screen.

How can I use the roadmaps feature to synchronise multiple teams/projects?
