The AI keeps working when you leave the chat

After you send a message, the AI finishes its answer even if you close the app, open another tab or start a new chat. When you come back, your question is in the chat and the answer goes on from where it is. Up to 3 chats of a shop can answer at the same time; on the phone the chat list marks a chat that is still answering, and you see "Answer ready" when it lands. Do not send the message again: that spends a second AI request. Only the Stop button stops an answer. This topic is answer-only for the AI: there is nothing to switch on.
