Trying to verify the "add screen for thanking the customer" step (where you complete the flow) and now getting an error when trying to verify it.  Here is what I did based on the different post I have seen:

• Closed all of the browser windows (even rebooted the laptop for good measure)
• Cleared cache on Chrome
• Tested on Chrome incognito screen
• Tested on Firefox

I developed this on a new Trailhead Playground environment, so no other projects have been created yet on it.
I keep on getting the same error:
"Challenge not yet complete:  here's what's wrong:
There was an unexpected error while verifying this challenge.  Usually this is due to some pre-existing configuration or code in the challenge Org.  We recommend using a new Developer Edition to check this challenge.  If you are using a new DE and seeing this error, please post to the developer forums and reference error ID: AFYIRYKX"


Any help would be greeatly appreciated!  Thanks
