Has something like „people who bought this also bought“ tapping into Order history or „people who looked at this have also looked at“ tapping into Sessions ever been done?

this only creates relations between products, it’s not using sessions or order history, correct?

you can backfill some relationships for the “order history” part. the session part should be covered with https://github.com/solidusio-contrib/solidus_recently_viewed

Sure

Thank you
