Widget does not appear

1. Check that the script is placed before the </head> tag in theme.liquid (or that App Embed is enabled).
2. Make sure the theme is published and that you are testing on the live store, not in preview mode.
3. Do a hard refresh (Ctrl+F5 or Cmd+Shift+R) to clear the browser cache.
4. Test in private browsing to rule out extensions (Adblock, etc.).
5. Make sure you are not using two installation methods simultaneously.
