I can’t answer C quiz module 7 because I can’t use uppercase letters on iPhone SE there. Is it just me?

Question

The answer should possibly be FILE written in uppercase letters. Unfortunately I can’t change to uppercase letters there (if I change nevertheless lowercase letters get printed) so that I can’t answer the question and cannot proceed in the course.

Does someone else face this problem?
Where can I report bugs?

Answer 1

Those module quizes are case insensitive. Means correct answer's case doesn't matter.

Also I just revisited the quiz and can confirm all the answers are correct, you may be typing in wrong answer.

Answer 2

Thanks a lot, you‘re right!
