ChatGPT Apps triggers Auth flow when MCP transport is stateless

Posted in the other thread but wanted to post here as well and apologize for this experience - this was due to an internal caching issue that we identified and rolled back earlier today. The issue started yesterday morning and lasted until ~ 3pm today. It affected a portion of users that were attempting to authenticate/connect into their ChatGPT apps.
