I just logged out of the openai classic app, when I try to login again I get :

It CodexApp, QuickChat only ... Codex project chats and chat in the Web-App not impacted, newer ChatGPT app on iPhone works fine too.
Just noticed it's working now... I think they fixed the api call and token validation
The Codex app Quckchat works for me again. But when I try to login into der chatgpt desktop app I get :
``
Failed with error 401, message: Unable to verify authorization token``all working again for me
