Glenn Gabe asked Google’s Danny Sullivan is there any Google’s product review update as well along with the Google June 2021 Core Update. The answer of Danny Sullivan is NO. If a Product review site showing impact, then this might be due to Core Update.
Glenn Gabe shared a tweet showing how 2 different sites impacted with a product review update in April. And saw another impact when the core update is rolled out.
Changes you're seeing around the core update are almost certainly related to that.

This signifies almost all sites of any type can be impacted by google’s core update due to its any of the signal. But its nice that Google did not release any product review update.
