[Shopify] Why isn't Autocomplete / InstantSearch working?

If you’ve installed the Algolia plugin for the first time, or moved to a new theme, and Autocomplete or InstantSearch aren't visible, then:

1. Make sure Autocomplete / InstantSearch is enabled.
   
   • The Autocomplete option is available on the Search Options tab in the Search basics section.
   • The InstantSearch option is available on the Search Options tab in the Search basics section.
     
     
2. Ensure that the CSS selector for both these options is targeting the correct element.
   
   
3. Go to the Enable Algolia on a theme section on the Search Options tab, and select the Enable on a new theme option.

After this, Autocomplete / InstantSearch should work as expected.
