Hi Touqeer!
This is Donna from the Mixpanel Support team 🙂
Apologies for any confusion caused by this - it looks like there is a permissions issue with the example Board.
As a workaround, you can access the Demo Project directly by:
1. Go to Mixpanel’s Demo Project through the Mixpanel UI shown in the screenshot below
2. Select B2B/SaaS
3. Search for the Hot Shard Board
You can then copy the board to your project via "Use this Board".
