@trevor.doodes are you looking to update the user information? Can you ensure that you are using an Auth0 Management APIv2 token to achieve this? In order to get a token for the Management API we would need to set the audience for it: .audience("https://YOUR_AUTH0_DOMAIN/api/v2/") . Can you let me know if you were able to solve your issue?
