I am in a similar situation like yours, trying to vary content based on language. Did this solution worked for you in Quiz?
<span lang="en" class="multilang"></span>
<span lang="es" class="multilang"></span>
If yes, did you have to do anything special to make it work?
Above solution works for us in Courses but when we use the same solution in quizz it doesnt work. It shows both English and Spanish content
Appreciate any help here.
