You’re presumably referring this release note:
Added server-controlled order of related content on media detail pages
I think you’re interpreting that to mean that the user can define the order of all the “related” rows on a media details/preplay page, but that’s not what this means.
Previously, the order of that content on the page was semi-hardcoded in the web app itself. With this change, the web app now displays things in an order specified in the response that the server sends. That’s still a set order, but it’s coming from the server and so can change if a future release of the server decides to order things differently. It cannot currently be set or altered by the user, sorry.
