I cannot logout gpt for all device, or even a single device

I cannot log out from all devices. I use Google to log in, and here’s what I’ve tried:

  • Changing Google password
  • Disconnecting linked apps (ChatGPT) in Google
  • Using 2FA login in GPT and Google
  • GPT: Settings - Security - Disconnect from all devices

However, login sessions are still maintained on other devices. Even when I disconnect from all devices using Safari on iPad and then open the app in a same device, it’s still connected. This seems to be a bug or a potentially serious security risk - in this situation, users could easily believe they are safely “logged out”. Please let me know if there are any other solutions.

One additional thing is, I never let my Ipad know the NEW password for the Google but still ChatGPT session works. that means changing a password is uselss, which is generally considered very safe and direct solution in these situation.
