We have enabled the automatic migration of Classic to New Quizzes. When we import QTI files, though, they always fail to load as New Quizzes. If we disabled New Quiz Migration, it works. Why does it only work for Classic Quizzes? Are there any guaranteed tools that will generate QTI files that will import correctly as New Quizzes? I can get ChatGPT to fix the QTI files for me, but I wanted to know if there are any dedicated QTI file generators that work with New Quizzes?
