Hi everyone,
I'm using Next.js 15 (canary) with React 19 and ReactDOM 19. I installed React DevTools, but when I try to use the Profiling tab, it says:
"Profiling support requires either a development or profiling build of React v16.5+."
I am running the app in development mode (
How can I enable profiling in React DevTools with my current setup? Is React 19 supported, or do I need to downgrade to React 18?
Thanks in advance!
