Could someone help?  For the trailhead Creating a Lighnting Component challenge, why am I getting the message  
Challenge Not yet complete... here's what's wrong:  Could not find a Lightning Record Page named 'Account Record Page'.


Thank you!

Can someone help me?

I keep getting this result: "The 'Sales Rep Win Rates' report chart does not appear to be using a vertical bar chart" although the report dóes show a vertical bar chart.
It's in:  "Create Reports and Dashboards for Sales and Marketing Managers; "Visualize Your Data"

I tried by doing the whole trail again in a fresh/new dev org, but keep getting the same result.

I'm having all sorts of problems trying to complete the challenge for the sharing rules section of this module. I feel like I have everything setup properly but still get this error message:
Challenge Not yet complete... here's what's wrong: 
The Sharing Set is not setup with proper Case access. Please check the requirements.

Sharing set name is "Share cases with customers"
Applies to Profiles: Customer Community User
Access Granted: Case - User:Account = Case:Account - Read/Write

What am I missing
