Your key only works on your website

Every website has one live key. The chatbot only answers when that key is used on the website you registered (www is fine).

That is intentional: someone who copies your snippet onto another site will not get answers from your pages.

Refresh key on Domains issues a new key and the old one stops working immediately. Update the snippet everywhere (theme, Tag Manager, test site, live site). There is no overlap window.

If the chatbot refuses to load, the page address is probably not the one you registered. Add the missing address as another website (if your plan allows) or make sure visitors use the same address you registered.

Opening a saved page from your computer will not work. The chatbot needs to run on your live website.
