Italian "Learn New Words" Program not loading

I am in the middle of the “Italian 2” course. I notice that the above mentioned program is not working. Has anyone else noticed the same? If so, how do they continue learning the course?

There is a bug that can prevent the automatic start of the next chapter - i. e. the app thinks there’s still one or more words to learn on a given level and will thus generate the error message you mentioned when you try to learn. Just move on manually to the next level by tapping it and then tap the learn button and you should be fine.
