Suggested replies follow the shopper's language

Some English-speaking shoppers saw suggested reply buttons written in French under an answer written in English. Tapping one sends the button's message as the shopper's own turn, so the conversation could then drift into French.

The assistant is now told to write both the button label and the message it sends in the language of the shopper's latest message, the same rule its answer follows. When that message has no clear language, such as a product name or a single word, it keeps the language the conversation has used so far. The examples it learns from now cover English, French and German instead of French only. This applies to every agent version that uses suggested replies, with nothing to change on your side.

One limit remains. The buttons follow the assistant's answer, so when the answer itself comes out in another language than the shopper's, the buttons do too. That is a separate problem and is not fixed by this change.
