@ormewq Thank you for your feedback. While not incorrect, using いらっしゃる in this sentence would make the whole phrase considerably more verbose/long-winded. That being said, since it is not incorrect, we will add a hint to this alternative answer. Thank you for drawing this to our attention. Cheers!
@lopicake In one of our future updates we would like to add the option to view related grammar points before you even type in an answer. This, of course, would be a hidden, toggleable feature. We hope that features like these will help make it easier to determine exactly what answer Bunpro is looking for. Stay tuned. Cheers!
@seanblue Thank you for your feedback. We will see what we can do. Cheers!
