When using the Multisite concept for E-commerce, data is stored on each site. That means that if we have a Swedish site, a Danish site and an English site, we’ll get reviews in each language for each site (most likeley). However; Danish people and Swedish people can understand English, so as such English reviews add value on both the Danish and the Swedish site – but not vice versa. This functionality gives the option of syncing reviews between sites in a neat way.
User experience: As an administrator, I can choose to sync reviews between multisites
Benefits: Increase review visibility – Automatically increase the number of reviews between multisites so that you don’t have to copy-paste.
