On web and phone, When I press “TRANSLATE SENTENCE” on sentence mode, it brings back the same Korean sentence I’m trying to translate in the first place. The catch is, I have added English translations myself in the edit lesson menu. So it makes no sense as to why they are not showing up.
You had Korean selected both as your study and dictionary language and that was the issue.
I just changed your dictionary language to English manually, please give it another try.
