Personalisation doesn't work.
Firefox 141 Linux
Error message: "Failed to update Personalization profile"
It doesn't accept my instructions:
"I want answers delivered in a strictly rational, informative, and matter-of-fact tone without conversational elements, greetings, sign-offs, or emotional language. I want the answer to start with a short summary addressing the core question. I want bullet points, numbered lists, or inline text for structure to be used and no tables. I want double quotation marks for quotes. I don't want long dashes. I want only international units. I want the answers in English unless correcting grammar in another language."
