how to disable automatic sharing of board

[yuweiming]

I have one team workspace and three system workspace.

When I create a board and modify the search scope of the filter to project in (A, B, C),

I found this board was shared to project workspace A, B, C.

how to disable automatic sharing of board?

Hi @yuweiming welcome to the Atlassian Community!

The board is based on the filter. If the filter is shared with the people who need to see the issues on the board, then that filter is shared automatically. If you would make the board filter private, then other people would not see any issues on the (team workspace) board.

Thank you for your answer.
I want every board to have their own filter in system workspace,
and the team workspace can converge the issues of three systems.
Is there any way to do it?
