I'm running react 16.12.0, react-dom 16.12.0 and scheduler 0.19.1.On a production build, when I view Profiler tab it says:Profiling not supported. Profiling support requires either a development or production-profiling build of React v16.5+. Learn more at fb.me/react-profiling. And on a development build, I get this popup when I try to access React DevTools. The console doesn't show the Profiler tab either.
