I have a magento EE v2.4.1 website. my products disappear from PLP (category pages) automatically sometimes or appear on wrong category pages. this issue seems to be due to indexing, because when we are using magento's scheduled indexing or update on save indexing, this issue happens after few hours or days. but whenever we run manual re-index from CLI, the issue resolved for all products. but again appears after few days by itself. And also the issue is happening with the new products which are being added after the version upgrade to EE 2.4.1, the issue not happening with the old products imported from old version. and this issue also happening even if products are in stock.
Does anybody have the idea why this happening, or anyone ever faced this type of issue ?
