But sometimes I meet these criteria and it just counts it as "correct" altogether, without alerting me to the typo! It's very disconcerting! So I often come to the comment-section to check if I really did it right. (But often the comments won't load either! Quite annoying!)
Ky: Unfortunately, Duolingo has been know to err, so maybe that happened to you. Use the Flag/Report button for that.
Also, note that we can't see the result of your translation; most of us are just learners as you are. So if you want someone's feedback on that situation, you could take a screen-shot, put it online and link to it in your comment.
BTW, given the limitations on Duolingo's teaching style, I find that these comment pages often contain helpful info that clarifies or expands upon the exercise.
If your device often has trouble loading these comments, you might try a different device (phone, tablet, computer) or a different network connection (cellular, wifi, LAN cable), or even a different location, depending on what options you may have.
Suggestion for the future: To get the best feedback on what you typed, take a screenshot, put it online and link to it here. It's always possible that you made an error that you didn't notice, and a screenshot should show what correction it gave you. Also, if you know you gave the right answer, the way to notify the developers directly is with the flag/report button.
