Typing "yes" to Biddy now confirms the change
When Biddy offers a change, it shows a confirmation card with a Confirm button. If you typed "yes" instead of tapping the button, nothing ran. Sometimes Biddy even said the change was underway, for example "Generating the proposal now", when it hadn't started.
Now a plain "yes", "do it", "ok" or "go ahead", typed or spoken, confirms the card, exactly like tapping the button. That works when the card is the last thing in the chat.
If your answer says more than yes, like "yes, but make it $11,000", Biddy reads it as a new request and shows you a fresh card. Biddy also won't say a change is happening until you've confirmed it.
