I have been studying the Idioms of the Italian language. Lesson 1 tells me it contains a list of words that include "dire" and "meglio". I have played this lesson everyday, I keep getting the same phrases over and over. I am never introduced to a new phrase. I happened to be on Duolingo from the website and in the same Idioms lesson was introduced to three phrases I've never before seen.
Why is the app repeating the same five phrases and making me say it, spell it, choose the correct words, translate it, etc.? Why are the new phrases not in the rotation? I'm tired of "meno male" being the first phrase EVERY TIME I open the lesson.
