Visit https://en.wikipedia.org/wiki/Special:ContentTranslation?page=Comoment&from=fr&to=en&targettitle=Comoment&version=1&useskin=minerva (tool in desktop minerva) and ContentTranslation loads and is usable.
It seems many ContentTranslation modules are not being loaded on mobile. There seems no reason why this should be the case.
Please ensure
"targets": [ "desktop", "mobile" ],
is defined on all modules.
Mobile site is loaded on tablet devices, so it seems important for this to work.
