I have four hands-on org, but none of them is working.
On clicking on "Launch":
1st hands-on org: open Playground Starter with a welcome message.
2nd & & 4th hands-on org: open setup page.
When I am clicking on "Check Challenge" I received either error on different hands-on org even if I completed every step as directed in the challenge.
Challenge not yet complete in user_name@gmail.com
1. Whoops, looks like there was a problem. Please try again
2. We can’t find a Visualforce page named 'StationCheck'.
Please help to resolve it.
It is normal for Launch to open either the Playground Starter landing page or the Setup page. Identify the Playground where you completed the challenge. Go to the relevant module/unit, and in the Challenge section(bottom), choose the right hands-on org and clicking Launch.
If the Playground is not already connected, click Connect Org to link it to the module.
Once the correct Playground is connected, click Check Challenge to earn points to validate your work and complete the challenge.
