I have a multilingual MS Forms, with primary language English, and secondary language French. It works fine in many browsers on many computers, but not very well in Safari on iOS. On my iPhoneX, when I switch the form to French, the resulting page is partly French and partly English. The title of the form is displayed in the French version, the questions on the form are in English, the prompts such as "Sélectionnez votre réponse" (Choose an answer) are in French, the buttons and notices at the bottom are in French. It's all intertwined. I could understand something in one language or the other, but I am puzzled (to say the least) at seeing a mix of languages in this browser, but still working fine in other browsers!
