Hi
I am doing the trailhead learnings and need to refresh my data in force.com to do the tests in Trailhead. How can I refresh my force.com data back to the initial start (when creating first time a test account)

I am unable to complete the hands-on challenge "Create a lens that shows which industry is buying the most laptops" I continue to receive the following error even after multiple attempts.

"Challenge Not yet complete... here's what's wrong: 
The 'Top Laptop Industry' lens does not appear to have the correct query. Please check the requirements and ensure everything is setup correctly."

I just completed this challenge and it's not working.

I've done everything according to the requirements and still get this message:
"Challenge Not yet complete... here's what's wrong:
The 'Sales Pipeline Overview' lens does not appear to have the correct query. Please check the requirements and ensure everything is setup correctly."



Also, the "Copy and Paste Results between Lenses" is no longer possible for me. Can't find copy or paste...
