We fixed two issues in the assistant.
- Ratings stay where you put them. Rating an answer with a thumbs up or down now applies to that specific message. Previously a new rating could replace an earlier one in the same conversation.
- Clearer message when an email is already in use. When you ask the assistant to add a teacher and the email address already belongs to someone at your business, it now tells you who that is and how to give them the instructor role, instead of simply failing. It never changes anyone's role on its own.
