Bug

What is the current behavior?
The profiler tab only shows this message even though I have a version greater than 16.5.

Something strange on the console is this message and just appears when the extension is active.

Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?
React 16.9.0
React DevTools 4.0.6-a39d9c3
