I launched the developer edition, created the My Data app and activated it.  I get this error: Challenge Not yet complete... here's what's wrong: 
The 'MyData' Lightning App was not found.

Any ideas why it's not finding the app.  I see it there and it's activated.

I'm doing the simple lightning components challenge and have hit this problem in my existing trailhead org and a brand new dev org that I've just created:

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: QVWBQHAG

Error says Challenge not yet complete... here's what's wrong: 
You do not have the correct account fields in the 'New Detailed Account' publisher action

Trailhead Challenge says
Add the Account Name, Type, Rating and Fax fields to the compact layout.

What am I doing wrong?


Thanks!
