How to leave a closed board?

[PX]

A board was closed. I am still  seeing its cards in Trello search. I can't leave the board.

I browsed the manual https://support.atlassian.com/trello/docs/leaving-a-board-in-trello/ -> Leave closed boards https://trello.com/support/leave-closed-board gives me 404. 

How to leave a closed board in Trello?

Hi

I think you should write directly to Trello support to see if they can help you, because you could abandon the workspace, but if you have other boards, you might lose them.

(I'm in the same boat as PX) Free trello accounts can only get community support, not the real support, so that option doesnt work. 🙄
