I’m experiencing an issue in my Magento 2 store where products randomly disappear from category view on the storefront. The problem resolves itself temporarily after a hard refresh of the page, but then reappears later. This inconsistency is causing a significant impact on user experience and sales.

Details of the issue:

• Products are correctly assigned to categories in the Magento Admin Panel.
• The issue occurs randomly and affects different categories.
• Products have stock managed (qty and salable qty), and visibility is set to “Catalog, Search.”
• Product status is enabled.
• Clearing cache and reindexing temporarily fixes the issue until it happens again.
• No errors related to this issue are found in Magento logs.

Magento Version : 2.4.3
We are using Opensearch (AWS).

After indexing products, they become visible temporarily, but we continue to encounter the same issue afterward.

I’m seeking advice on how to troubleshoot and permanently resolve this issue. Any insights or suggestions would be greatly appreciated.

Thank you for your help!

Cleared Magento cache (php bin/magento cache:clean and php bin/magento cache:flush).
Reindexed Magento data (php bin/magento indexer:reindex).
Verified category and product assignments.
Checked for any conflicting extensions or customizations.
