Hello,

I'm getting this error when trying to check challenge in the Lightning Experience Rollout Superbadge for challenge 6. I've tried a different org, and I've tried recreating the Key Sales Data and Communications app. 


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 (DE) to check this challenge. If you're using a new DE and seeing this error, please post to the developer forums and reference error id: RVLNKIMN
