We use Jira Next-Gen with Atlassians cloud-hosting.
I moved Issues from "in progress" into "Done" state. However, when I want to close the current Sprint, Jira still reports all Issues as "open" and asks me to transfer them over into the next sprint.
Within the Jira Next-gen project there is no option to "close" an issue.
If "done" is not the right state to complete an issue, how can I achieve that?
