Hi @Martin, Heidi (SE GP T SP PS) ,
It’s a hidden feature in SharePoint Communication Site, so, It won’t be available on the Site collection features page. However, let’s just activate the “Rating” feature alone using PowerShell.
#Site URL
$SiteURL = "https://crescent.sharepoint.com/sites/Portal"
#Connect to SharePoint Online site
Connect-PnPOnline $SiteURL -Interactive
#Enable Rating Feature
Enable-PnPFeature –identity 915c240e-a6cc-49b8-8b2c-0bff8b553ed3 -Scope site
Remember to replace the variable $SiteURLwith your own.
This will activate the Rating feature for all lists and libraries in the site! After my testing, it works fine in my Communication Site!
