React18 - ReactQueryDevtools not showing

I’m running:

  • Win11
  • Edge
  • @tanstack/react-query-devtools": “4.28”


The little flower icon just doesn’t show on my page.
I don’t get any errors or warning in console

Have already tried:

  • Chrome, Firefox
  • Reloading VSCode
  • stopping / starting ‘npm run dev’
  • google suggests this used to be an issue, but latest versions should have it.

Any thoughts?
Anyone else get this issue?

Urgh - I’m an idiot. I still have my NODE_ENV set to “production” from previous learning. Switching it back to “development” fixed it
