Losing issues after completing a Sprint

[Nguyễn Văn Hoàng Tùng]

Hi guys,

I can't find Closed issues after completing a Sprint also I can't find those completed Sprints.

Is there any way to keep them?

Thanks

Have you tried a search for the issues?

Issues don't go anywhere just because they are done at the end of a sprint and hence don't appear in the backlog or active board.  They just don't need to be displayed there any more, they're still in the projects, just closed.
