The chat isn’t showing, an answer is wrong, a booking is missing or tests stall.

- [The chat isn't showing](https://www.meetdarwin.ai/help/fix-a-problem/chat-not-showing): Fix a Darwin chat that doesn't appear on your website: check that the agent is live, the domain is allowed, the site tag is installed, and the opening message isn't hidden.
- [Fix an answer](https://www.meetdarwin.ai/help/fix-a-problem/fix-an-answer): Fix a wrong or incomplete answer from your agent: find the conversation, check the page it should answer from in Agent Studio → Knowledge, add the missing facts, and ask again in the preview.
- [A booking is missing](https://www.meetdarwin.ai/help/fix-a-problem/booking-missing): Fix a booking that didn't work or doesn't show in Darwin: check the calendar connection in Integrations → Scheduling, the meeting's status in Meetings, and the conversation it came from.
- [Experiments aren't moving](https://www.meetdarwin.ai/help/fix-a-problem/experiments-not-moving): Find out why Darwin's opening experiments aren't starting or finishing: automatic testing is off, the background check is delayed, a page needs more views, the test limit is reached, or a winner is waiting for you.
