We tried closing the tickets and the page is just freezing and the ticket is not getting closed.
Below are the troubleshooting steps we followed
1) Done project re-indexing
2) Tried moving the tickets into the Closed column in their scrum boards.
3) Checked user role to make sure we have enough access to close the tickets
4) Checked field configuration scheme to confirm there are no mandatory fields.
There is no luck even after trying the above steps.
We found a behavior associated with this project and wondering this could be the root cause of this issue.
