Hello, at the bottom of each English Wikipedia article (and maybe on other language versions) there are three "Related Articles" at the bottom of each article. This used to be a Gadget in the Beta tab. The Beta Gadget is now gone, but Related-Articles still works on the Mobile-view of Wikipedia. This is a good thing, and desired. For example, I use Related-Articles as a carrot to help newbies learn to edit Wikidata.
The issue is that Related-Articles is no longer on the Desktop-view of English Wikipedia (and maybe on other language versions). I discussed this with Leila of WMF and she suggested contacting the Reading Team, but I feel this is a bug, and therefore suitable as a Phabricator task.
In this screenshot, using Brion Vibber's Mobile-view simulator, you can see that Desktop-view lacks Related-Articles, whereas Mobile-view includes the three Related-Articles:
