This is apparently possible in Jira 8.11.0, whatever that is (https://jira.atlassian.com/browse/JSWSERVER-10805). I've got a 'next-gen' project in Jira cloud, and can't see a way to enable this setting.
Our company has several teams, each with their own Jira Project. Our sprints are not relevant to each other. Yet for some reason my project's sprints are not even showing up at the top of the dropdown when creating a ticket in that project.
We have to scroll down to find our own project's sprints!
Is this setting also possible in Next-Gen projects, or cloud Jira in general?
