When to use it
If someone copies your embed code onto a site you do not own, the allowlist keeps your reviews off it. It also keeps a widget meant for one brand off another brand's site when you manage several.
Things to check
- Add every domain you use, including a staging or preview domain, or the widget will not show there.
- If a widget stops showing after you add domains, the page's domain is probably missing from the list. See widget not showing.
