We are actively investigating an issue with Azure AD B2C. The JWT tokens issued by the service don't have the 'kid' value pair in the headers. Some customers may experience errors while attempting to validate the signatures of tokens issued by Azure AD B2c.

We are working to resolve this issue ASAP and apologize for the inconvenience.
