I can't use my TP because the launcher is not showing up in my hands-on challenge.

Hi Cory,

Sorry for this issue you are encountering.

May I request you please double check if the same issue is being faced only with a particular trailhead module or did you face the same issue with respect to all trailhead modules.

If you have an issue with any particular module then I would suggest you please clear all the cache and cookies and give a try which should probably do the trick.

Still, if the problem persists then kindly reach out to the trailhead support at the below email address. Hope this helps.

Kindly mark this as solved if the issue is resolved.

Thanks,
Nagendra
