Now I need to recover some vital information from this board, is there any way to recover those information in Atlassian's servers ?
Did you make a backup ? If you are in cloud you can ask atlassian if they have a backup but i think it will be hard to find something deleted x month ago.
Yes, we are on the clouds will ask them, do you have any contact. there ?
by the way, thank for your answer
