How do I make mumsnet dark mode?

Just that really. Web version not app.

Profile icon in the top corner.

Settings > more settings > display > select dark mode

When I click that and click apply, it just refreshes the page and remains in light mode, with the radio button reset.

This is how I do it
Down arrow near the top right
