I have upgraded algolia/algoliasearch-client-php to version 1.28.0, algolia/algoliasearch-magento-2 to version 1.9.1 and I am using Magento 2.1.8 version.
The reason to upgrade Algolia was to test Merchandising feature available. But I am not able to see products under Algolia Merchandising tab in sub-category. Adding screen shot for same.
My question is, How to get products under Algolia Merchandising tab in order to set products positions? Please let me know in case I am missing something.
