Representative feedback from a user in regards to the matter:
I was happy using your Wiki App but not being able to switch between languages of an article is a major regression to me. Not only can I no longer link to an article easily to readers using a different language than I am but I can as well no longer get more information about a topic by checking the article page in a different language that I understand.
We often receive this kind of feedback on OTRS. So I think it’s worth to explore alternatives and perform usability or A/B testing on it to evaluate a better solution.
