Finishing the last challenge of the picklist administration Trailhead Module results in an error message, I cannot solve - see screenshot. Any ideas? I promoted the field to a global picklist, created the new field based on the global value set as requested...

I'm trying to complete the "Set Up Single Sign-On for Your Internal Users" Trailhead challenge, and was able to execute the description of the challenge successfully. However, I'm getting the following error when checking the challenge on Trailhead:
 

Challenge Not yet complete... here's what's wrong: 
Could not find SAML Enabled in your org's setup audit trail. Make sure that you have 'SAML Enabled' checked under 'Federated Single Sign-On Using SAML' in your org's 'Single Sign-On Settings'.

I've reviewed the settings, and "SAML Enabled" is true, and I'm connected to the right org when doing the challenge. Has anyone else encountered this?

Hi,
    i am currently doing the above mentioned challenge in the salesforce trailhead. I creatd a permission set and assigned it to the user like it was mentioned and even logged in using the two factor authentication method. but still it is showing challenge not complete. Is there any reason to this. I don't know what i am missing. The following is the error message i received

Challenge Not yet complete... here's what's wrong:
Could not find a user's successful login using two-factor authentication. Make sure you successfully login at least once and that you are prompted for a second factor of authentication

Any help wpuld be appreciated
