Hi @Chris Lenz ,
Make sure that the claims are added in the optional_claims and that they are added in the accessToken and that the profile scope is added to the request as described here. Note that the family_name and given_name claims are always included in v1.0 Azure AD tokens, but not included in v2.0 tokens unless requested. Typically this issue occurs if the scope is missing or the claims are not included.
If you check the browser console you can also see if there is any policy that could be blocking the request.
