Temporary Chat Refresh Causes “Page Not Found” with HTTP 431 Error (Session Not Restored)

Hey @Deepak_S1! That’s definitely not expected. After refreshing, it should redirect you to a new Temporary Chat screen, not a “Page Not Found.”
When you get a sec, try incognito/private browsing first, then a different browser, and clearing cache/cookies if needed. If none of that helps, please reach out to support@openai.com so they can investigate further.
