Oh, it worked! but I didn't know that until after I committed it by clicking Post. It gave every impression of NOT having worked.
Please may I humbly suggest, could the help article I quoted above, be updated? I'd be pleased to be a guinea pig to test or comment on a new version.
Thankyou for paying attention

I can't get this to work. I've seen https://www.chess.com/article/view/how-to-use-the-chesscom-diagr and that's ten years out of date.
Here's an attempt
So I clicked on the little board icon above this post, pasted a FEN, made about three moves each side, it ends in checkmate win for Black. Clicked Insert. Back to this draft post. But before I click Post, all I see so far is a grey checkerboard with a dimmed pencil icon in the middle. No moves, no pieces, nothing else.
Please, what am I doing wrong or missing?
