Quizzes not saving chosen answers (says questions were skipped)

Hello,

We have created a course using LearnPress, and everything is working great except for the quizzes – the marked answers are not being saved, and the final result is that the questions were simply skipped.

We have already added the LearnPress course to the exclusion list for our cache plugin (following a suggestion found in another forum post), but the problem still persists.

Do you know why the quizzes are not saving the marked answers? Could you please help us fix this?

Thank you!
