Hello,
I have been using Auth0 with ADFS connection for months but I’m suddenly unable to sign in since Thursday, August 20th 2020.
No change has been made in my code, and I experience the same using Postman.
Request

audience: “https://MY_TENANT.eu.auth0.com/api/v2/”
client_id: “foo”
grant_type: “http://auth0.com/oauth/grant-type/password-realm”
password: “bar”
realm: “TENANT-adfs”
scope: “email profile openid”
username: “USER@MAIL.com”
Response
HTTP status: 400

"error":"invalid_request",
