You may have noticed the following warning on your Algolia App for Shopify:
Starting from Dec 31, 2023 Shopify will no longer support theme injections.
The only required action would be to follow this guide to migrate your settings to metafield configurations: https://www.algolia.com/doc/integration/shopify/sending-and-managing-data/algolia-config/?client=ruby#migrating-to-metafield-configurations
This will ensure that your future changes on Algolia settings (e.g. facets, sort orders, etc) continues to be reflected on your front-end after Shopify stops supporting theme injections.
