Same experience with Google. I was setting up SSO for a new web application and set off some AI flag on a sub domain for our company website. For 2 weeks every visitor saw a warning that out site was a phishing scam. Nightmare. With no recourse. No number to call. No person to talk to. No actual explanation of the error (I still don't know exactly what I got wrong). I just took it down, waited, and prayed.
