Hello there,
I'm facing this issue with Elasticsearch 7.6.2 with Magento 2.4. Anyone have an idea?

The issue was running multiple Magento instances on the same server. You need to have a different index names for each website. You can specify Magento index name in Magento backend (configuration/catalog)

I am running in completely same issue. I cant see option in configuration/catalog where i can set different index name.
Can you specify exactly what need to be done to fix this issue?
Thank you!

Go to STORES > CONFIGURATION > CATALOG > CATALOG > CATALOG SEARCH > Elasticsearch Index Prefix. Set a different prefix for each store, any random one for each. Reindex and flush cache on each store.

Hello,

could you please describe how to change prefix for each store? The field "Elasticsearch Index Prefix" is available only when the Scope is "default config" - sreen attached.

When I switch to Store (I have to two) the field is not available at all.

Please help. Thank you. Viktor
