Dear Sir / Madam,
I am from zhwikiversity. There is user feedback that using modern skin, they are only able to use source editing not VE. The button isn't there. If there are no wikidata item, adding other language will remain grey. I checked with local IA, and confirmed it's nothing we can do by tweaking mediawiki namespace locally. Could you look into the problems. Thanks a lot.
(P.s. my 1st ticket, pardon if anything screw up)
