The widget disappears when I navigate my app

This applies to single-page apps (React, Vue, and similar) — sites that load one HTML shell and then swap content as the visitor clicks around, without a full page reload.

How it's supposed to work

You load the widget once, from the app's shell HTML or root component (see React / Vue). The widget then watches for in-app route changes and re-applies itself on each one — so it stays present and a visitor's choices carry across navigations. You do not re-inject the script on every route.

If it loads first, then drops on navigation

1. Confirm you load it once, in the right place. It belongs in the shell index.html (or your root component), not inside an individual route/page component that unmounts when you navigate away. If it's mounted per-route, it gets torn down on navigation — move it to the root.

1. Don't add it multiple times. Loading the script in more than one place can cause it to fight itself. The recommended React/Vue snippets guard against double-loading by checking for an existing data-site script — keep that guard. Load it in exactly one place.

1. Hard-reload to retest. After changing where you load it, do a full refresh (not just an in-app navigation) so the new setup initializes cleanly, then navigate around again.

If it never appears at all

That's a different problem — start with The widget isn't showing at all.
