Hello,

Arwiki experienced user complained that today he can't link articles to each others by language section on sidebar, as this section does not appear in articles available in one language.

English Wikipedia Article

The user trying to link this new Arabic Wikipedia article to enwiki one, but he can't find language section on sidebar, and to link it should go to Wikidata item and linked it manually

I noticed same things on all articles that exist on one language, and this Not the expected behavior

Expected behavior = existence of language section sidebar with "add links" button.

Note:

• Maybe it's Google Chrome issue (81.0.4044.138)?
• Same thing happened previously on 2013 here -- T51139
