When I answer a question wrong, It will not let me put the correct romaji answer in the box, so I cannot get any further in the course at all! For example, when trying to write “I think” in romaji, it only lets me get as far as "to " and then the answer bar always flashes red. I have tried every possible letter, space then letter and every other way posible but nothing is accepted.
Please help as I would like to complete the course.
