Unable to update user authentication methods

Hi 1993satya 

Thank you for your question. I just tried on my test environment and it works fine. I also tried using "New user authentication methods experience" and that also worked without any issues.

Could you please provide more details?

Are you using an admin account?

Does it happen when you try to update "user authentication methods" for any user?

Are you trying to update the phone number or Email?

Thank you

Dav,
