Hi, getting a weird issue. It's only happening with one user. They are getting flagged with: Sign-in error code
50076: Due to a configuration change you must use MFA to access 'resource'.
We use 3rd party MFA so we don't have any MFA policies enforced. Checked user, they are set the same as everyone else, MFA is disabled.
Any ideas?
Thanks!
