Can't even read past conversations that are deemed "too long": redirected to homepage with error "This conversation is too long, please start a new one."

Welcome to the community @loveandwisdom!

Here’s few things you can test:

• Log out and back in.
• Try a different browser.
• Clear your cache/cookies.
• Test in a private/incognito window.
• Update the ChatGPT app if you’re using mobile.
• Check whether the same error appears in both the app and the web version.

If possible, try opening the conversation from your chat history/sidebar instead of through Search and see if the behavior is different.
