I am going through the module "Manage Salesforce Data Access" and I just clicked on the "Validate Challenge" button, but, instead of checking for challenge completion, it vanished the entire challenge section from the module. Any experience with that?

Hi @Silvio Zavala

I am from the Trailhead help team.  Can you please go through the below workarounds and then check?

- Make sure your browser is UptoDate

- Clear your browser history/cookies

- Check in the Incognito window/Private browser

- Give it a try in other browsers like Edge and Safari. 

Thank you!
