React.js Developer Tool

The React.js Developer Tool is not showing up on the Tab on Chrome or Firefox when you do a CTRL-SHIFT-I for a tab running a React app. I wonder if others have the same issue. I’ve seen it reported on google search but no solution. Thanks.

I’m having trouble with this article too (https://www.codecademy.com/paths/web-development/tracks/front-end-applications-with-react/modules/react-development-setup-and-ravenous-part-1/informationals/ready-react-developer-tools) . My “React” tab shows up as two different tabs “Components” and “Profiler” and Components tab looks similar to the “React” tab in the article. The App doesn’t expand like the article says. Can’t really follow the article. :woman_shrugging:
