What inter-issue dependencies are supported in Advanced Roadmaps?

[gordon_varney]

I can do things like A must be finished before B can start.

I'd like to do more complex such as:

* A and B need to finish together

* D can start # days after C starts or D can start # days after C ends

Hello @gordon_varney 

Currently Jira Cloud Plans support just one dependency type; A must finish before B can start.

For more complex dependency options you would need to consider a third party app that can integrate with Jira, from the Atlassian Marketplace. There are several such apps available, but I have not worked with them so I don't have a specific recommendation.
