Vue js not detected on Code Pen Challengers (Vue Mastery)

I’m learning along with the Vue Mastery videos and enjoying it. But shouldn’t vue.js dev tools work on the challenges?

It’s not finding any vue.js on the challenges.

Hi there

Have you tried to view the application in the "debug mode’ view?
If you are a free user, you will need to fork a project so that you have the “debug mode” option.
I think Vue devtools works only in debug mode


Thanks Dehsen
