Am able to see same sprint(Sprint1) in 2 different project boards say Project-A and project-B. I did following this.
in one project-B, i created new sprint(sprint2) and moved all the issues(Sprint1) to the new sprint. Even after doing this am able to see that sprint(Sprint1) in the board. now am not able to see any issues for that sprint(Sprint1) but in reports section under sprint report and viewing in issue navigator am able to see issues for sprint(Sprint1) but not able to see those issues in the board for sprint1. another thing is, if i try to close sprint1 in project-B, it is closing sprint-1 in Project-A too. please help me on this
